Hi again guys. I have a couple questions for you. Hopefully I will get this thing smogged! OK, bought the car with a blown up engine. Found another complete engine from the same year car(3.4 also) and put it in. Had a few minor issues but got it running pretty good. I went down to smog it and the HC are at 10! CA the limit is 1.00. I have already changed plugs, wires, iac, tps, o2 sensors, secondary pump, filters, just about everything I can think of. Another thing I have noticed is it is terrible on gas. My local mechanic seems to think the injectors have been replaced with larger ones. He said the fuel pressure is right, the computer is working right, the map is working. It runs good. Hard to start at times. Am I looking at a bad cat? Wrong injectors? Worn out injectors? What else can affect the HC levels and make it run so rich? Thanks in advance for any help!
