Question about 1999 Dodge Intrepid
I got a MIS FIRE code a few weeks back that began to casue my car to high idle. As soon as I cleared the code the problem went away. But now I'm geeting a very strong smell of fuel and have checked for leaks and have not found any. Since I bought the car I've gotten approx 20 miles to the gallon and that has not changed. Fuel lasting the same as before. Any idea what can be the problem.
Please see the diagram attached and test it. Othewise you must RUN the scanner/computer for easy diagnostic and fix it.
God bless you

Harry,there are two failure modes for your problem. If you get a C.E.L. when the problem happens, you will be able to retrieve the codes and will probably find TPS circuit failure codes.The TPS (or APPS) has a flat spot and at the magic position, will drop the engine to an idle.A couple of full throttle applications on the pedal will usually cure the porblem for the moment.Replace the sensor assembly (very expensive).The other mode is a similar drop to idle but without a C.E.L. This is usually corrected by shutting the truck off and re-starting it.This indicates a brain failure on the VP44 injection pump.The solder joints become crystallised on the circuit board from excessive heat cycles. This will create poor connections on the board and cause a loss of power and drop to idle.You can either replace the pump (also very expensive) or if you are mechanically inclined, you can source a brain and solenoid assembly and replace it on the pump. Hope this helps. Ken

If it has never had plugs changed, i would suggest it. It can make a big difference.
Labor time is .8 hrs + 6 plugs = $80 - $150.
Take your car to a parts place and they will usually check and clear your light for free.
Firestone likes to up-sell everything, $650 is way too much for a basic tune up.
