coil pack changed, still idles like buckaroo - Saxperience

tristan · 11th August 2006, 19:30

ive changed the coil pack from a local scrappy and fitted it on but there still is idleing like a bukaroo makeing a chuging noise, but some times it sounds like it is good for a couple of seconds then stops, i changed the standard rockers for roller rockers as mine were all noisey and i wanted the engine to be less noisey put it back togeather and it was doing this, had it in the garage ever sinse as i have been respraying the car myself and this is the last thing to sort out apart for the new windscreen, gotta fix this as there is a bet on with my mate that i cant get it working in 2 weeks, if anybody can help as i would love to have my car working again.

checked your spark plugs

tristan · 11th August 2006, 19:34

yep spark plugs changed and ht's

deek06 · 11th August 2006, 19:37

could be 1 of your cylinders mate

tristan · 11th August 2006, 19:38

what would be wrong with it as it was working before i fiddled with it

deek06 · 11th August 2006, 19:41

hmm not sure mate maybe the coil pack from the scrappy aint working to well

tristan · 11th August 2006, 19:45

is it that likely for 2 coils to be broken as i found out the last coil was not sparking on cylinder 4 but the one i bought seems to be sparking on all 4

deek06 · 11th August 2006, 19:47

yeah after all you did buy it from a scrappy mate

tristan · 11th August 2006, 19:54

i have got a brand new coil but if it turns out not to be the coil i cannot take it back after it has been used as the spade termanals would be marcked, what do you think i should do, could it be possibly be anything else lick the ecu or the idle stablisation valve

deek06 · 11th August 2006, 20:01

im not sure mate sorry i cant help you further

tristan · 11th August 2006, 20:04

if anybody else can help please do as i want to drive

slammed_vtr · 11th August 2006, 22:29

ihad this and it was a gasket, is it losein power aswell?

erm this may or may not help. but mines was doing the same thing and i put a load of red-x in with the petrol a couple of times and it sorted the problem.

hope that helps.

i know what i did do before it started doing this i loosened the head and retightened it again as my head was leaking and it stopped it and a few weeks later i changed the normal rokers for roller rockers which really keeps the tappet noise down and helps higher up the revs but i did not change the head gasket again but i don’t know if that would the problem as the head was never taken off the car or moved so i just don’t know, and all the plugs, ht's and coil have been changed + a cannot drive the car as it barley idles

I had exactly the same problem - changed the coil pack, still chugged like a tractor. It was one of the fuel injectors in the end!

spencer_cammedvts · 13th August 2006, 14:14

my vts does this on idle. and then allof a sudden it will drop to about 400rpm then pick up again. and it will do that every say 30 second or so. its so annoying! car works fine but its just the chugging!

tristan · 13th August 2006, 14:19

i just whant to know what is going to be most likley to be my problem ive narrowed it down to 3 things?
head gasket is leaking
blocked injector
faulty wiring/sensors
just if you could tell me hat you think it could be? thanks

chrissyboy · 14th August 2006, 15:30

You say the problem started after changing over to roller rockers. Did you check the valve clearances afterwards. It could be that you have insufficient or no valve clearances which of course means that the valves will not close fully and you will be losing compression. I'd take the top off and check the clearances mate.

tristan · 15th August 2006, 13:58

i will check but the engine does run really rich which could be down to one of the sensors or some thing but will check and will get back 2u thanks

tristan · 15th August 2006, 14:06

as i got the head earler to change the head gasket as it was leaking oil and it may fix the problem, checked the clearances there all fine but i forgot the belt was not on and ive lost the timing as the camshaft is in the wrong place can anybody answer both of my questions as the both need fixing, thanks
