My car was running rough about four months ago, so my husband took it down and got it scanned, my check engine light had been on for a few weeks. The scan told us that the number four cylinder was not firing, so he replaced all of the plugs and plug wires, that fixed that problem but another one popped up. The radiator was losing water and overheating, so we thought I had a blown head gasket, so we tore apart the engine and replaced the drivers side head gasket and for good measure while we were in there we replaced the water pump and thermostat. That fixed that problem but guess what? Another one popped up. The car would not stay running at an idle, and the check engine light came back on. We replaced the throttle positioning sensor hoping that was it but it was not. We took it down and had it scanned again and it said oxygen sensors on the right and left bank, so we replaced those. But it did not fix the problem either. Check engine light came back on and read the EGR valve so we replaced that, no dice. Check engine light came back on and still scans saying EGR valve so we replace it again. Still the same problem. I was told that the catalytic converter could be clogged, so we replaced that. Still my car will not stay running at an idle when it is cold. After it has warmed up it will stay running just fine but I cannot afford the gas to sit in my car with the gas pedal pressed to keep it running for the fifteen minutes it takes to completely warm up. We have tried every thing, please help.
