I've a 1995 Sportage 4 x 4 2.0 single overhead cam, a 5 speed, with 116k miles. I drove it for about 1 year when it started hesitating. To date I've replaced the fuel pump, checked the pickup sock in the tank (ok), changed plugs/wires/air and fuel filters, cleaned the throttle body inside and out, replaced the position sensor, replaced the mass airflow sensor, the pcv valve, and checked the egr valve which seems to be working ok and pulled a vacuum on it and the diaphram holds. I also checked the fuel pump pressure and although it's been a while and I can't recall the exact pressure, I do remember it's well within factory specs. And for what good it does, over time I've ran several bottles of Lucas injector cleaner through it. It hesitates and idles a little rough but what in the heck am I missing? Possibly a bad cam or crankshaft position sensor? The check engine bulb works but never comes on other then when I first start it as it should. Other then this issue it runs great, get's 25mpg, and is fun to drive!
have the same problem?
