I searched the forum and found a thread from a couple years ago where the person had kind of the same problem as me and said he fixed it but never said what it was. When I saw the thread I was hoping to get some clues but ended up being s dead end.
So anyway I have this 92 Dakota with a 5.2. This truck has been a topic of discussion here before.
after I got a the bugs worked out the truck has ran great until recently it's been acting up. I'm betting because of the colder temps we have been getting in Tx.
So here's the issue. Truck starts up and runs perfectly fine until you shut it down and come back after 15ish minutes then it runs like it has a huge vacuum leak and runs very rich strong fuel smell. After 2-3 minutes of this it just goes back to normal.
It's only after the truck has completely warmed up and only when it's been shut down for 15 or so minutes. Only in that particular window of time. And will always go away after a couple minutes after start up.
I'm thinking o2 sensor acting up or egr solenoid or maybe coolant temp sensor?
Something going on the fritz during that window of cool down that's telling the pcm to dump a lot of fuel.
Anyone got any ideas
