I just used an OBDII reader today and got codes P1237 through P1242. I found out what they mean as far as Fuel Injector open circuit, but what exactly does that mean? I have seen a few posts with people saying that their cars were runnning crappy because of this or that the car just doesn't start.
My car for the most part is running fine. Although I am geting really bad gas mileage and sometime my car hesitates at lower speeds.
I had changed out my spark plugs last year to Iridium plugs. Could the aftermarket plugs be causing the problem?
And for that matter could the mass air flow sensor(MAF) be causing this?
