I have a 1.8 ts 16v in the garage and it has a misfire.I have checked the plugs,leads were on wrong,cam belt set up,as it came to me with this problem and by the look of it some one had put a cambelt on it and it was missing bolts in the cam belt cover also bits hanging of where they should have been bolted on so.I have checked the cam setup with locks and every thing now line up and all the leads are on correctly but it is still missing.Does anybody have any ideas please as it is doing my nut in !!!
Thanks Daiblack and JackPJW the reason i know its not the leads is because i have swope my stuff onto this car and still the problems are there.What is this about a Lambda sensor,the cars only done 60'000 and has a receipt saying that it has had one already but i wonder if it was a new or second hand one?I am doing a compression test tomorrow night as well as taking the lambda off mine and putting it on this one but first is a 1.8 and a 2 ltr sensor the same ?
Also when it is ticking over the sensor/valve i think it is the VAE valve makes a cracking sound i have swoped this over from mine and still i get this sound but the funny thing is it sound normal for a second and then back to a lumpy juddering engine .
If you do the compression test on No. 2 again, drop a some oil into the chamber (no more than a capfull) and repeat the test.
If you have a compression reading then the piston rings (or piston) are knackered, if no compression then it is likely to be the head.
The oil has the effect of sealing the piston rings to give compression,
