Problems with stalling at lights. EGR, PCV or IAC?
Hi. I'm having a problem where car stalls sometimes after driving highway it seems. RPM's Sit at 600 and slowly fade until engine off. I'm thinking it's the EGR valve but hoping it's just PCV. Anyone ever clean the EGR with carburetor cleaner? Does it last if you do? I thought it was the spark plugs but those are new now and same issue. I've even noticed the car stalling for like a second on the highway then engine light came on for one second and then normal but that is rare as it only happened 2 times but still. I've got the 3.5 engine with only 81 000 kms or 49 700 Miles on it. Thing sat for most of it's life if that helps.
