A friend came to me today with a problem on his son's truck. '98 Ram 1500 4x4 with 360 motor 90,xxx miles. I'll try to remember what he told me. Was driving along fine and the motor just dropped into a rough run situation, sputtering like it wanted to die. Code checked said #1 and #2 injector bad/missfire. Replaced #1 injector and ran a little better. Replaced #2 and ran worse than before. He has done a complete tuneup, plugs, wires, etc. Replaced the crank sensor, and I believe the cam sensor. Still runs rough, worse on idle. Still says #1 and #2 bad. Swapped #1 with #3 and still gives #1 bad.

Has check fuel pressure and it is good. Checked injector wiring and also looks good. He had mentioned that he put a scan tool (what it was I don't know) that showed that the injectors were working, tool shows flashing light when injector fires. I mentioned checking all the grounds, and possibly injector wiring with a meter. The difficult part is that Dad is here in Michigan and son is in Tennessee. Although he is working, he can't afford a trip to the dealer, but can't keep throwing parts at it either. So I'm wondering if anyone had any ideas I could pass along.
