97 Ranger 2.3 No Power Rough Idle
I bought a 97 ranger with a 2.3 and 5-speed. It has 99,000 miles. It idles rough and has no power. It wont do over 60 on flat ground. It pings pretty much all the time while driving. My mechanic friends and I have checked everything we can think of with no results.
I just put new plugs and wires in. We have checked the EGR, MAF, timing, air filter, and compression and all of them checked out. Fuel pressure is 32psi at idle and around 35 while revving. The fuel pump is ok and we replaced the filter and regulator and rail. The pressure is still the same.
I swapped both coil packs and the computer with my friends ranger which runs great, but nothing changed. I loosened the exhaust right after the headers but it ran the same, so Im assuming its not a plugged exhaust. There are probably other things I have done that I dont remember right now.
I am swapping the injectors on Wednesday but im not optimistic. Sorry about the long story, but I dont know what else to try and could use some help!
