not to sure what it is .???
i have a 2007 GT 2.0 pet lusso done 50k brought it at 42k TWO years ago
ive changed the bat, 2 an S5 battery, changed the spark plus to NGK, and had new coils put in all 4
but at times the car struggles abit to fire up, i had a mechanic repair a valve problem it had a while ago and he did mention that the screws that were holding the ignition coils down were to long and there was alil play with the coils while they were in place,
the only other thing i can think of , is the injectors may need cleaning , but i have know idea how to get to them let alone taking them out, buying an ultra sonic cleaning bath thinging
isnt a problem as there a few online , its just getting to them and taking them out
any other suggestions ??
