the higher your car idles the more gas it burns and the hotter the cylinders get meaning preignition. Also too they may not apply but the RPM gauge could be off by x% i have a 92 camaro that reads 1500 rmps when its at cold idle and i have been to lazy to fix it. Never assume that your idle is fine when its over 1000 rpms. Also if it back fires through the SC or the NA intake it can cause a broken time gear tooth. Do that to many times and your computer will be frying the engine. so yeah no high idle lol. I know BillBoost is correct because it is electrical and they do fail from time to time. Personally before i say its the gauge i spray with carb cleaner to make sure i have no vacuum leaks then check the voltage to make sure im with in range.Originally Posted by Dakoda
