I assumed it was vacuum related, but haven't found anything. It idles high and surges on occasion. Ideas?

0507 which I believe is a generic "high idle" or some such thing.Originally Posted by tanz45
Your pot stash catch on fire? That might be the cause of your "High Idle"
what about 02s? Definitely have Virgil hook up to it and see what the sensors are putting to the PCM.
See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
true you may need to replace the intake gaskets buddy, really need Louis to check the tune out also
2006 silverado SS....Clifford Jr...turbo coming soon
1970 Chevelle ly6 swap....d1 coming soon
Dirty IAC, dirty throttle body, vacuum leaks as mentioned.
Squirel in the intake.
99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
the surge could be from the TPS sensor not reading properly...It could be bouncing from 0-5% and causing it to surge. You got anyone handy with HPtuners to plug it in and check it, or a scan tool..
