tfarm Posted June 29, 2005 Share Posted June 29, 2005 '97 Outback ltd. 2.5l engine with 135K miles. Tbelt, cam seals, and ignition coil and plugs were replaced at 125K. Car idles very rough and kicks on CEL with misfire code on #1. With the AC on there is no rough idle. Swapped two fuel injectors and seemed to be a little better but didn't solve the rough idle. Mechanic said it could be electrical or it could be that the heads need to be rebuilt. ANY SUGGESTIONS WOULD BE APPRECIATED. Thanks, Jr. Quote Link to comment Share on other sites More sharing options...

Cougar Posted June 30, 2005 Share Posted June 30, 2005 Turning on the AC should set the idle up a little faster. Have you checked the TPS for dirty contacts? Quote Link to comment Share on other sites More sharing options...
Setright Posted July 1, 2005 Share Posted July 1, 2005 SOunds like an Idle AIr Control valve problem. Search on here, and you should find lots of info on cleaning it Quote Link to comment Share on other sites More sharing options...
