Okay so been having problems with my 88 mgm. Car would turn on fine then idle up and down and run ruff almost like it would misfire then die would have the step on gas to keep it running. Took it to a mechanic that I know all he did was disconnect the vacuum line for the egr and fixed it. Then sly told me it was those little things on the passenger side fender( not sure what they were called pic is at bottom). So I’ve been driving like that for a while with egr disconnect. about a month later check engine light comes on code 33 and 34. So i go to the junkyard and find a newer one( part on fender) hoping it was that. Reconnected the vacuum line for the egr. And works fine no more stalling like it did before. But check engine light is still coming on works great no stalls i then replace cap and rotors about a few days later then all of a sudden it would stall again but this time it idle just fine it dont fell like a mis fire or anything just runs then dies and idea what I could be.
