I bought a 1996 Ranger 3.0 from a dealer with 60k miles. It's real clean but after driving a while, I noticed it idles very rough. While waiting at a light, I can feel the truck shaking back and forth. It runs great otherwise. I brought it back within warrantee period 2 times for a total of 6 days. Honda dealer sent it to the local Ford dealer where they replaced the air sensor. They tell me nothing is wrong with it...the computer shows nothing...but it idles exactly the same. Is this normal? Is there anything I can do to smooth the idle? It drives me crazy.
Thanks for any help.
