Hi all, I am still having some strange problems with my 3.9 01 Dakota. I will say take a half hour trip to the store,it runs great,go in for 30 min,come back out start it up and begin to drive out of the parking lot and it seems like the idle goes high and low,back and forth,like its revving high and then dropping down,at times in reverse it will stall out.
Another thing i notice is durign the same situation above,when i go back and try to start,i will turn the key and crank for say 4-5 seconds and it wont start,stop for a second then hit the key again and it fires right up.
I had an oldsmobile that sort of did this and the problem was a mass airflow sensor.
Anyone have any ideas what my problem might be? I just changed all the wires and plugs,air filter and pcv valve,thinking these would fix the problem but they didnt Thanks Rob
