I have done my research before asking you guys on this but I can't seem to put my finger on what the issue is. Latly only at idle after coming to a stop, the rpm's would go really low and want to stale then jump back up a little. Today the same thing happened but worse and there was a little hesitation on take off. But after gaining speed I am totally fine. Shifts fine and cruises fine at all speeds. SO I was thinking either a vaccum leak ( I have checked the hoses but who knows) or a O2 sensor going bad or the MAT sensor is going bad (engine temperature sensor that determines air-fuel ratio I do have a small intake/exhaust manifold gasket leak but I don't see how that would create such a hesitation. I had the gasket go about two years ago and was running fine. I have upgraded all my grounds, I have a mopar CPS and drilled out the top mounting hole, cleaned all connectors and relays, plugs and distributor are fine, air filter is fine. I would appreciate the input.
