Engine Mechanical problem
1999 Dodge Intrepid 6 cyl Automatic 83,000 miles

I have had this car to the repair shop 2 times in one month. While driving down the road the engine will sputter and several times has shut off. When they hook the computer up to it there are NO codes. So I have changed spark plugs, check coils and wiring, replaced egr valve (ouch) they say its not the fuel pump, acted like there was water in gas added stuff to correct that . Still I can feel it missing in the gas peddle it is very suddle now but seems to be constantly having a slight miss to it sort of like your hitting bumps in the road. Could this be transmission? Still something with sensors?What are the possibilities?Thanks so much

Hi:
First I would like to know what the fuel pressure reading was from the pump. Also, does the engine seem to have the power it has had in the past?

Hi thanks so much for the reply.I do not know the readings for the fuel pump they did not record them at the time (so they say) stated that it must have been between 55 and 65 or this would have indicated that there was a problem to them. Anyway the engine does seem to have the same power it has always had just some hesitation when you mash it into passing gear thank you again for your reply. Rachel

Hi:
I wish I could provide better info for you, but without codes and it having good fuel pressure, a hundred things could be causing it. There are some general inspections you could do. For example, check under the hood for vacuum leaks. Listen for hissing sounds. Also, and don't laugh, at night time, in the dark, start the car and open the hood. Look for sparks or arcing from the spark plug wires and things like that.

If it continues to get worse, it should kick a code in the computer. Let me know if I can be more help.
