Misfiring With Plugs

[LScottBell]

Hi

I had ngk plugs in my saxo vtr (2001) plate but the engine light came on says about a misfire cylinder 1 so i went out and bought the bosch super 4's put them in and started and the car was sounding like a tractor and shuddering so bad.. So i put 3 of the ngk's back because 1 NGK got damaged so now i have 3 ngk's in and 1 bosch and the car is running terrible its misfiring when driving along would this make a difference the 3 to 1 on the plugs ? And how tight do they go cause i didnt overtighten them but enough to make them secure

Any help would be appreciated thanks ;)

Try a new set of plug leads

A coilpack ? The car ran before i changed them the odd shudder but now its bad it drives then really gives the car a shake i will just get ngk's again tomorrow & swap that bosch around

How tight do spark plugs need to go ?

They have a crush washer so basically keep going until it gets tight then keep going and it will stop

Cheers for the replys Lads ;)

I will put NGK's back in tomorrow and see how it goes ;)

Bosch made my engine (vauxhall) and mates engine (Renault) misfire as well.

I think they should stop making spark plugs

My car was unreal this morning i mean to get to 30 i had to floor it in second and it took a good 20 seconds and the noise was honestly like a tractor lol

Yes bosch should look at making thier plugs better thier selling plugs called *super* but infact they make the car run worse than your ordinary cheap plugs.. I bet some folk will have had a decent experience with them but for me it was bad

Im gonna put a new coil pack in anyways as i reckon the old one is on its way out cause my cars shudders slightly when idle.. Lumpy
