I've read all the posts on this site...i replace fuel injector relays, OVP, tune ups, actual fuel injectors...you name it. I replaced one freak'n motor mount on the passager side, no idle problems at all. Amazing! the engine does not sit tilted having only changed one or anything. Just a 40 minute job that changed my entire relationship with my rig...i love it once agian!!!!
btw, the other one is for sale on ebay for 20 bucks.
