We are having trouble figureing out what to do next. Our 98 sable decided that it wanted to stop starting. When turning the key car cranks and trys to start. Check engine light was on for insuff. egr. We have replaced the egr and the pvc valve. Car now seems to start easyier however if we are just letting the car idle it dies (while making a few poping nosies here and there). Prior to replacing the EGR and PVC valve if we were to leave the car for 5-8 hours it would start and die within the 1st couple of trys but after that we couldn't get it to turn over again. In the morning we are going to clean the MAF sensor and see if that does anything. Does anyone have any ideals on what to try next :eek: Seems to run ok when pressing on gas pedal.

Thanks for any help you can offer.

Did you replace the hose atop pcv valve as theyre known for leaking on your yr. and eng. Also, did you replace the egr valve or dpfe (egr pressure sensor)? Highly unlikely egr valve replacement will cure your insuff. egr flow code (po401). Its usually the dpfe sensor and/or a carboned up passageway behind the throttle body gasket to the egr valve. If check eng. light is still on, have it rechecked for codes (free at autozone).

We didn't replace that hose....would that cause this problem? We did replace the egr valve not the dpfe. We were just out there and the car started almost no problems. We did replace the fuel filter today to and there doesn't seem to be a problem with the fuel pump. However after the car had run for 5 min he turned it off and when he restarted it, it ran for about 1 min before it slowly died. However this time when it died it didn't putter or pop.

Thanks
