rpmdiag :

Thanks for your question. Sorry you're having car problems. If I go off line, just leave a message and I'll be right back. DO NOT leave feedback yet. Either the fuel you are using is not good enough or the KNOCK sensor on your engine is not working. Let me know if you need more help. Thanks, Ron
