Engine Performance problem
1999 Dodge Dakota 6 cyl Four Wheel Drive Automatic 142000 miles
I have a nightmare on my hands. My truck for the past year has been giving me headaches. It starts losing power, backfiring while idling and driving down the road. If you put the gas pedal to the floor it will clear up. If you shift to neutral while driving and turn off the key and restart the truck it is fine. A local mechanic has tried to help with the problem. He could find no problems with his computer. The engine light just came on finally after a year. P0132 and P0172 came up. I have replaced so far the fuel pump, coil, dist. Cap, rotor, plugs, plug wires, engine computer. It is still doing the same thing. It does not matter if it is hot or cold. Wet or dry. It might go 2 weeks without doing it or it might do it every 2 minutes. I have ran cleaner through the fuel system and also pulled the gas tank and cleaned it in case of water or dirt. Modifications to the truck include, Flow master 40 series muffler, no cat. Royal purple oil with flowmaster oil filter, k& n stock filter replacement, synthetic fluids throughout everything. Please help I purchased the truck cheap and willing to throw some money at it if I need to.
