I have a engine wiring problem with my 1994 Dodge Ram 1500; When I drive in forward gear the engine shakes and runs very rough...plus it back fires when I step on the gas pedal - No power at all!!
But, when I drive it in reverse gear, the engine runs smooth and fine...No back fire or running rough!!!
My truck has been parked for about a month now, because of this problem, I had a complete tuned-up in the fall of 2010, everything was fine up to this point. My buddy and I checked the spark plugs wires to see if they were not loose and also made sure the distributor cap was secure...and we checked the spark plugs to see if they were gapped right.
Everything checked out okay!
When my friend and I were just about to give up, we tried one more thing - my friend put the truck in forward gear and held the brake while giving it some gas; Under the hood there's a bunch of wires in a black curly tube on the body of the truck above the engine...I started shaking that tube of wires and the engine smoothe it self out and wasn't running rough anymore.
So, I drove it around for about 20 minutes everything was fine, I guess once the engine got hot...the problem started up again - running rough, back firing, No power when I stepped on the gas. This only happen's in forward gear, it doesn't happen in reverse gear!!
We think it's a bad wire some where,that's broken, rusty or hitting against the engine, but where do I look...what wire would cause this type of problem?
