Need some ideas before I burn the car. Idles slightly lumpy and is down on power, feels very flat, it's had new leads,plugs, cap, arm, icv, tps, I've stripped the afm and cleaned it, gone over in inlet numerous times checked every single pipe and gasket for air leaks. Nothing. Where do I go next? Coolant temp sensor? Any help appreciated and it's only really this week it's started doing it, somethings changed
Anyone?
