Question:

I need help,  just got my 1992 explorer 4×4 sport out of the shop, just a simple oil and filter change and I had the throttle body cleaned, no big deal.  Half way home (25 miles away) I get a terrible vibration in the driveline only at a constant speed.  When I accelerate or take my foot off the gas it quits.  Any suggestions???? thank you Kevin

Based on what you had done it could be possible that something with the Throttle Body cleaning is causing the engine to stumble.   Check that the rubber air inlet hose was secured to the front of the throttle body securely and that it did not fall off or come loose. Just a wild guess on a little info.  Be sure to let us know what the fix is. Bert — REMOVE *NOSPAM* FROM EMAIL ADRESS BEFORE REPLYING —
