Looking for suggestions...my idle/vacuum drops when I put my windows up or down.(just one example) I have had strange idle problems since I bought the car and now I am starting to think that maybe it has been electric related all along.

Most of the grounds in the engine compartment have been replaced and I have changed the ECU and ISC to rule those out.

Any ideas?


Thanks

 

Try a capasitor on the battery or even a new battery. Sounds like the extra load slows everything down. Just for peice of mind take the alt. off and have its amp out put checked as well, can never be to safe. Just my .02

 

Battery is only a couple months old and I had the alternater checked out last year and it was fine. Any other ideas?
