Ok so i am at a loss i have replaced the fuel injector seals, intake gasket 2 times, tb gasket, new coolent temp sensor, put a differtant Thermo time switch in, changed out the idle switch with a used one, swapped in 3 differant ISV, pretty sure that the co mix is right and timing is about 8 degree. Here is the problem it idles too high, when its cold it misses and it gets **** fuel mileage. The plugs im using are the 3 prong bosch super coppers Would a bad o2 sensor make it idle too high???
