Search this forum this category all forums for All words Any words Whole Phrase (search options) Auto Repair Home>> Automotive Repair>> Car Troubleshooting Rangerj User Oct 3, 2010, 7:42 PM Post #1 of 6 (2593 views) Erratic idle Sign In 1993 Mercury grand Marquis 4.6 auto 95,000 miles. recently the engine will rev up and then down it does this consistently. The car runs fine but I need to fix this issue.I sprayed throttle body cleaner into the TB,but it didn't change the idle.Any tips?Thanks Sidom Veteran / Moderator Oct 3, 2010, 9:39 PM Post #2 of 6 (2590 views) Re: Erratic idle Sign In I would make sure there isn't any vacuum leaks 1st. Then block off the idle air bypass in the throttle body. If the idles goes low and stabilizes you may have a bad IAC motor (idle air control) Rangerj User Oct 4, 2010, 2:33 AM Post #3 of 6 (2583 views) Re: Erratic idle Sign In Thanks Sidom,I will try this.
