Hi, I have a 1995 LeSabre with the 3.8L v6 that revs at high RPMs when the A/C is. It does not do this when the A/C is off. It seems to coincide possibly with A/C on and the engine reaching its normal operating tempurature. I've replaced the throttle position sensor and this doesn't see to have helped. Any ideas what could be causing this? I'm thinking it may be an electrical problem or bad sensor elsewhere. As an aside, the car did have the air bag light on for the longest time and a mechanic discovered that there was a short in one of the horns that kept blowing a shared fuse ( #10? ). Perhaps this is a sign of other electrical issues, one being my racing engine problem?
Any help on the racing engine would be appreciated.
Thanks.
