the rpm gauge goes crazy after having a remote start taken out...the remote start caused problems and thats why I had it removed....I had to reset my key to even get the car started after having it removed....its something that I could've done before getting the remote start taken out but I didnt know about it until I found an 800 number online...the check engine light, oil, antifreeze light stay on also....they flicker..this is so annoying
