hi guys i have been having some trouble with misfire and jerking slightly over the last month, but its been getting worse and worse and today it wouldnt boost over 0.6bar (1.1 normal) and it wouldnt start, also it has a really bad misfire and backfire when cold but gets a bit betting when warm.

i have changed some bit over the last 4 weeks so i think it wont be these.

-Lambda sensor
-turbo intake pipe
-coolant temp sonsor
-Vacume pipes
-sparkplugs
-maf sensor (senond hand) but working for sure.

Thanks David

 

anyone

 

do a engine pressuure check see if all cylinders are firing correctly.i had similar problem and done the pressure check cylinder 4 had 0 pressure.rebuild

 

i took it to the garage and they said it was coil packs, had them changed, took it home left it a few hour to go cold and still the same problem.

 

take it back to em and say that hasn't fixed it, want my money back, and now they can have a second go.
