Contour Enthusiasts Group Archives Forums General Troubleshooting HELP worried about my SVT....

Hey I recently fixed a CEL that read EGR valve ristricted air flow.. so we cleaned it out and the CEL was gone.. then the same day at night... it came back on. my car began to have rough idling and like a bubbleing noise coming from the engine on idle.. The car staled twice one time my oil light flased befor stalling.. help what do you think this is???

Check your codes again. Sometimes when you clean the EGR circuits[ports and valve] carbon gets loosened but maybe you didnt get out all the pieces, so later on when the engine was running some of the carbon worked its way into the seat of the EGR valve and is causing problems again. When you have CEL's always pull the codes, it will get you started in the right direction. Hope this helps.

Had a 4.6 Crown Vic that did the same thing. Tried cleaning out the EGR valve and got a temp fix. Replaced the EGR and everything was fine. (course on a V-8 it was a little more difficult)

thanks for the help guys im going to try to get a new EGR valve ad see it thast teh cause...

Before you layout for a new EGR, check that the passage AFTER the EGR is clear. The passage feeds EG into three slots in the flange on the intake manifold where the Throttle body mounts. Remove the throttle body, and make sure the grooves around the flange are free of crud, and if you.ve got comprssed air, blow out the passage (cast into the manifold) from the EGR to the the TB flange. If U don't have air, try working a 1/4" piece of rubber hose thru the passage from the egr end to the TB end. You'll be surprised at the crud that gets built up in there! Not a difficult (but messy) job, and if that's the culprit, even a new EGR valve will not help it. Good luck.
