Have a 1987 Ford Ranger. Fuel injected 2.3L engine. Problem: Bucks on acceleration. Computer tester indicates idle RPM problem, code 13 and improper EGR signal. Code 32. Tachometer indicates proper RPM. Scoped RPM signal, it gets to the computer. Checked EGR controlling solenoids. They?re functioning properly. Scoped EGR signal to computer. It?s getting there. Replaced EGR valve with a used one, problem not as bad, but still there. Error codes staying. Suspect either computer or EGR valve bad neither one of them is cheap. But I am. Any suggestions?
