96 3.5 stalls when driving - fixed! page 2
First thanks to everyone who has helped keep my 'Trep on the road with all the great help and advice.
History: I have a 1996 Intrepid with a 3.5 and 72,000 miles. To date I have replaced the plugs, wires (twice, last time at 70,000), coil pack (last month), and this past weekend the complete intake manifold gasket kit. I had been having lots of misfires, cyl 1 and 4, which I attributed to the coil pack. These mostly went away after replacing it. However, I started having severe fast idle problems just before replacing the coil pack. I figured this was the intake gaskets. I took the IAC out and cleaned it but it did not help at all. I also checked with the local Dodge dealer and he informed me the fuel rail recall had been complete prior to me purchasing the car. One week prior to installing the gasket kit I was driving home, about 65 mile trip each way, and the car began losing power and then slammed into gear, hard (this was at highway speeds). It did this several times. Once it flat out died, but restarted fairly easily. I parked the car until I could get the gaskets replace. The only codes in the computer were misfires.
Replaced the gaskets this weekend without any problems, thanks to the great directions on this site. The middle bolts on the intake were just over finger tight, I think I think I found my leak. Reassembled the engine - not to bad of a job. Started the car up and it idled right at 700 RPM, ran like a champ. Filled up the coolant and took it for a spin.
After about a twenty minute drive I began to feel like it was stalling again. Not as severe as before, but almost the same. Neutral idle was still around 700, in gear stopped it was down to around 500. Car was not low on fuel and there are no codes.
I have searched the site and came up with Cam and Crank sensors. Anyone have any other ideas?
