106 gti lost power please helppp

[PugGTI]

hi i have a 106 gti and it seems to have lost power

when i try putting my foot down its like it wants to go but keeps pulling back

it has like a little energy burst then bogs down

do you think its a coilpack/spark plug issue?

i havent long ago changed the plugs

it seems to be idling ok tho? sometimes has revd up n down a tiny little bit

someone also said to try fuel filter as it may be getting a sudden burst of fuel and then not getting enough to go any faster?

help pleaseee

[PugGTI]

Please does anyone have any ideas as I have to drive to manchester in the next few days so need to sort the problem as soon as I can

[saxojh]

Any warning lights on? (ECU)

[PugGTI]

No mate no lights

[atspeedracing]

map sensors sometimes cause similar problems to this.

[saxokid100]

No mate no lights

fuel filter,sounds blocked.............:y:

[PugGTI]

fuel filter,sounds blocked.............:y:

Ok mate will try changing that tomorrow and see if it's any better

thanks for the reply will keep you updated

[saxokid100]

thanks for the reply will keep you updated

let us no how you get on mate!!:y::p

[PugGTI]

Just been and got new fuel filter for the gti will be fitting it within the next couple hours will see how it is then :)

[PugGTI]

:wall: just pushed the white clip in pulled the filter and it snapped the fecking petrol pipe connector so now im knackered! :n:

where does the line goto? straight to the fuel tank? im guessing i need a new fuel line now from the tank to the filter?

:wall:

[PugGTI]

Anybody???

[PugGTI]

Finally changed the fuel filter on my gti but still missing it seems to have gotten worse like it's running on 3 cylinders but now it's worse and seems gutless like it's running on two cylinders or something

anyone have any ideas? Think it may be the coilpack the more u try to put ur foot down the more it bogs down you have to use low revs and slowly let the revs build up

[Saaamon]

I assume it was running fine just after you changed the plugs? Get someone too put it on the machine, you'll end up wasting money on parts you dont need if you start guessing.

[Boyes]

Personally I think it's coil pack or spark plugs as you said it ran fine before you changed them, could have a broke a connection on coil pack.

[PugGTI]

It was missing every now and again that was why changed the plugs but was the same after I changed them

[PugGTI]

Ok tried a few things today on my gti, took the throttle body off and gave it a good clean and the sensors on it

Is the idle control valve supposed to go in and out? As it seems to be very stuff and is spring loaded if you turn it then it flicks back

put it all back together and had a few opinions on it when you rev the car they all say it revs to easy to be misfiring but when you drive it's like it has no power and revs slowly

[PugGTI]

Anybody?

[PugGTI]

went and got another coil pack today and still seems as if it is missing any other ideas guys?

[PugGTI]

does anyone think this may be the crank sensor?

it seems to start easy enough thou

[lharrowing]

did you say you can slowly build revs up ?

[PugGTI]

Yea mate does build up but it's like it's not got the power of a gti jus kinda splutters abit

[PugGTI]

Bumppp

[Bickerton]

Unplug your lambda sensor and go for a drive, it it''s still the same it'll probably be that, theres a few guides floating about on how to test your lambda

[PugGTI]

i unplugged it and it didnt make no difference does that mean that its the sensor knackered?

[Bickerton]

i unplugged it and it didnt make no difference does that mean that its the sensor knackered?

It could yes, there are guides on here and 106owners on how to test your lambda

[Sophia_Bush]

spark plugs, coilpack, one of the temp sensors, map sensor try one of them.

Also try another set of injectors one of them could be slightly foobar

[PugGTI]

someone has just said to me it sounds like a valve has gone as it sounds like a kinda tappin noise when its running =(

[scottyr_VTR]

my 106 did this not long back but all it was in mine was something got suck in the inlet manifold?

[PugGTI]

what did you do? just remove the inlet?

[Bickerton]

what did you do? just remove the inlet?

Tested the lambda properly yet?

[PugGTI]

it seems like its missing a guden mate, i unplugged the lambda and it made no difference at all

[Bickerton]

it seems like its missing a guden mate, i unplugged the lambda and it made no difference at all

That's my point, now search and find out how to test the lambda itself

[PugGTI]

I have also unplugged two sensors ontop of the throttle body and it still runs the same no different

[scottyr_VTR]

i just took the inlet manifold of and had a look

[c20xejay]

my gf,s C2 had the same problem she needed a new accel pedal(sensor) one she had was reading wrong or something

[PugGTI]

i think im going to try get hold of a throttle body with the 4 sensors on it and a map sensors and if its still the same i think im going to remove my head and take a look at everything and change the headgasket, cambelt and water pump whilst im there

[Bickerton]

No point until you've tested the lambda properly..

[PugGTI]

this wouldnt cause it to only be running on 3 cylinders and make a clicking kinda noise thou would it?

[Bickerton]

The idle would sound similar to 3 cylinders yes, ut would merely be underfueling.
Compression test will check cylinders, but i reckon no point at this time

[PugGTI]

i disconnected lambda and drove it still seems the same but i have also tried disconnecting the top 2 sensors ontop of the inlet and also the bottom one and its still the same

[shayne_vtr]

mate i had a mates car with the same problem it is deffo a fuel issue,you need to individually check all the components that factor fuel delivery and burn,what you need is a mate with a gti, swap lambda then test then swap back swap coolant temp sensor then test then swap back,swap the throttle body test swap back,on my mates it turned out to be the timing has slid out on the vernier,if ur cams sound noisey id start ther haha, but get someone proffessional to do it un less u have dial guages and relevant knowledge

[shayne_vtr]

It could yes, there are guides on here and 106owners on how to test your lambda

id give up he really dont seem to be listening

[Bickerton]

id give up he really dont seem to be listening

I have tried to get this point across a few times pretty clearly haven't i?
Though i wasn't being helpful enough ;)

[PugGTI]

Found the how to on 106owners but don't have anything to flame the lambda

[Bickerton]

Lighter ;)

[PugGTI]

Ok mate will try find a big enough spanner and remove the lambda tomo if weather ain't to bad and let u kno how I get on

[Bickerton]

Could also possibly try a gas hob to heat it up?Dunno how practical this method would be

[PugGTI]

What would be your next guess if lambda is ok? I can get inlet manifold with tb and all sensors and injectors for 50£ shall I give that a shot if lambda is ok

[shayne_vtr]

22mm mate a shifter (adjustable) will do

[Bickerton]

Next guess (could be alot of things) would be air temp sensor, thats the sensor coming into the bottom of TB or possiblt ECU temp sensor, thats the one that goes into your thermostat housing, both cheap sensors

[Slammed_Posi_Vtr]

As said, sounds like a MAP sensor to me

[PugGTI]

lambda sensor was all fine

going to change the head gasket n everything this weekend so i will check to see if the valves are all ok

how can i tell if my car has performance cams as i been told it has and someone said it will be on the end of the cam... which end is it stamped on? gearbox end of the cam or the pulley end

[PugGTI]

took the head off my car today and 3 spark plugs were kind of brownish and one was black does this mean the one that was black isnt working right?

here is some pictures of the plugs and a picture of the head

black plug

other plugs were like this...

and the head
http://img691.imageshack.us/img691/3871/img0081nn.jpg

as you can see pot 1 is black which is where the black sparkplug came out from and the others are a little brownish where the other plugs came from

any ideas why their like this?

[saxojh]

Im assuming that the black spark plug is the one corresponding to the black pot. If so then id say its overfuelling that cylinder. Injector related?

[PugGTI]

Yea mate black plug goes with the black pot, I been told that one isn't firing and to try a new injector?

[PugGTI]

Bumpppp

[PugGTI]

Anybody?

[PugGTI]

still having this problem with my car, someone said to try the injectors they said use a volt meter and test the ohm on each injector 2 were 14.x 1 was 12.x and one was 06.x does that mean the 06.x is knackered?

[adzvtr]

id hazzard a guess at yes m8, get them changed, i am having to rebuild whole bottom end because of an issue with fuelling, so wants sorting.

[PugGTI]

only strange thing is that the injector that has the low Ohmage is from pot number 2 but to me it looks like pot number 1 thats the one not working properly

could it just be that pot 1 is black and working and pot 2 is the one actually missing?

[PugGTI]

correction!!! injector that has the very low Ohm's is from pot 3

[PugGTI]

anybody?

[jordysaxobby]

Im havin the same problem mate. Did u manage to fix it in the end???

[JoshB]

Somehow I don't think he'll be an active member anymore...

The symptoms he was describing is a fuelling issue, mines got a slight stutter to it and the engine code it brought out was a faulty injector.

Ask your mates if you can borrow an injector and test yours one by one.

[Loz2212]

Has it got a cat? My mates was very similar to this and it turned out to be the cat that had collapsed. Drop it down from the exhaust and see if it revs more freely. A fucked lambda sensor would cause over-fuelling which could destroy the cat. Just a suggestion and a 2 minute job to tick the box.
