judder and hesitation
#1
hi.. after having my car serviced - spark plugs, air filter, fuel filter, oil filter and oil change, i noticed the car is hesitating at high revs - the pick up isnt smooth. Ive tried cleaning the solenoid with brake cleaning fluid but it hasnt made a difference. Anyone know what is wrong, all help appreciated.

What MY is it? If MY92-96 then the cause is probably either coil packs or ... when they changed the plugs they gapped them too wide. Gap should 0.7mm. Check the plugs/gaps first, if you have an early car as above and the gaps are ok then reduce to 0.6mm and see if it improves, if so then you need to change your coil packs.

The first thing I would do is reset the ECU, because the computer will have most likely made adjustments for the parts replaced, so now that everything is like it should be the ECU map is out.
