'88 IROC 5.7 (L98) is running 1300 rpms too high. Do you think voltage is too low? Bad ground? Any ideas?

LesPaulGoth 09-13-2006, 10:38 PM The tachs on these cars are well known for being wayyyyy off after a while. There is a resistor chip thing on the back of them that gets shot out at some point. There was a thread on this a few weeks ago, look it up, theres helpful info in there. robvas 09-13-2006, 11:07 PM Reset the base idle! onefastgta 09-14-2006, 01:02 PM Also clean the carbon from the inside of the throttle blades. | ||
