Hi I hope you are able to help me. My car has is a 99 Saturn SL manual. It has been running great since I bought it in october but recently I took it to get an emissions test and a host of codes came up. I fixed all of them but I am unable fix the code p0172. So far I have replaced the egr, iac, fuel purge valve, maf, ects, o2 sensor. Additionally I gave the car a tune up when I bought it; new plugs wires, coil, ect. So right now I am lost at trying to figure out what the problem might be. There are no vaccum leaks as far as I can tell and the only other problem might be the fuel injectors, but those to I can find no real problem with. The car runs beautiful except at start when it idles at about 1200-1500rpm until it is warm then at 800rpm. This I think is normal. Any ideas on how to fix this. I need to pass emissions so I can drive. Thanks
have the same problem?
