[QUOTE="aaron97, post: 6243329, member: 66010"] Well, no good news yet guys. He changed out all the seals and IMRC bearings and they are working out good and are not leaking at all now. But the codes are still there and now the car wont idle properly. Installed a new IAC since the old one was gummed up and that didnt help, installed a new TPS and that didnt help either. We're running out of things to change/clean/fix/inspect. At this point we are going to replace all the old vacuum lines with some new rubber ones. We did a pressure check on the system and it wont hold pressure, so its either got cracked/broken lines or bad components that the lines go to. But since the rubber hose is cheap, we will start there. Other than that, only things left to change are EGR (valve, vacuum solenoid, and pressure monitor), air/smog pump, fuel injectors. He is going to replace all the o-rings on the fuel injectors this time, since he has to pull in intake again to replace all the vacuum hoses and to make sure something didnt happen or get over looked on the last install, which might cause the idle problems.
