Hello,
I have been having problems with my 95 Ford Contour 2.0. It started with a 51 CEL code which I took to mean faulty coolant temp sensor, I replaced it and the CEL stayed although temp and fan seem fine. Then my check engine light starts coming on periodically and the car occasionally stalls at low RPM and will also occasionally buck or miss at high RPM (80K-100K). While this is happening I need to get an emmissions test, failed of course.
HC ppm 252 asm2525 test 287 curb idle test
CO% 7.78 " " pass
nox pass
Any ideas and are the two related, I have cleaned MAF, checked plugs and wires and they seem ok, used an Bosch cleaning product for jets etc.. Any help would really be appreciated.
Thanks
Mike
