I have noticed the last month my car has stueddered at stop lights..one time it felt like it was going to stall..i use premium gas but havent run any injector cleaner thru it yet.I have been reading on here and it seems a similar prolem is caused by the coils and spark plugs(which i need to change any way)..this looks like a pricey job this coil deal..cheapest ive found are 68 a piece and i would replace all six im guessing?..spark plugs are normal..60-100 a set depending on brand ect..Anyone have this same trouble and rectified it yet,..I really hope its not a vacume somewhere as im sure that is tough to find..I have also read something called an map sesor that could be dirty and need to be cleaned with a specific solvent..any help would be good...I should also mention..my brand of gas station just went belly up and i have switched from 93oct to 91oct.Again thanx lads:icon_play ing:

 

Hey Irish....

I would first check/change the easy stuff first.

Fuel filter----really easy and cheap.
Plugs----I buy NGK at like 3.00 a plg dude. 20.00 vs. 80-100???? NGK are great plugs and just put them in mine.

Coils---usually not the problem and i would just try plugs first. I reused mine at 110000.

Throw some fuel injector cleaner in too.

Vacuum leaks--- usually it throws codes if its effecting performance.

And if your car isnt throwing codes or CEL then i would do these things first. Cuz it could also be a few other things but i dont know your mileage and whatnot but these are simple maintenance things that could help your issue.

Also plugged cats, O2 sensors, etc.........

Good luck! Let me know if you need hints on how to do some of those or check the FAQ section.
