what's up guys, im at a loss here trying to figure this thing out, car runs great when cold but within 5-10min it develops a miss and hesitation especially under load, once in a while on a hard launch it will even backfire, ive checked everything fuel and ignition related and all is good, idle is low as well, never shuts off and always starts good, sometimes it will idle as low as 5-600 rpms and almost sounds like its got a cam witch im almost positive it does not...it is throwing a CEL for code 332 for egr valve opening not detected, I don't see any vac lines that are bad or missing, and when I did the test on the egr valve to see if it would sputter or stall with engine running and pulling the vac line off the top of the egr like its supposed to do....idle never changes. so is my egr valve stuck shut??? if so would it cause my hesitation and misfire when hot and low idle and HORRIBLE fuel mileage? any help would be greatly appreciated! thanks:thumbsup:
