My car Breaks up at about 1800 to 2400 RPM
What is your question?
I have tuned up my car with plugs, used Di-electric on the spark plug wires going to the plugs. Yet, it still breaks up at about 1800 to 2400 RPM. I have NO way to check if the plugs are firing OK. I have a scanner, it is a Innova 3160 Scan tool. I noticed the STFT B1 S2 were N/A also the Cat CMPL is N/A the HCat ENA is OFF, as are Evap EVA Cmpl, ACRF Fuel cmpl,HR Ena and EGR-ENA. I want a Good running car, and this is unsuitable. Thank You
