theres a link for checking engine codes in the faq. or consult the tsrm.. its in there.

whats your idle sound like after you got back from the test trip.
if you have a normal idle of what is it.. 700 for an na?

Almighty i took a a look at the code link. lG-7 code the one about the spark plugs is all i can come up with well we were working in the timing area we found alot of oil in the first silonder spark plug. we didnt check the others since to much work pulling off the throttle body. she idles fine with no shakes or falts. idles between 700 and 600 rpms at cold start then when wormed up stays between 800 and 700 rpms. its how she has been when i got her. could the timing off by one notch cause the engine to revv high but not gain any speed? if so then we will reset the timing. is there a way to keep the cams from moving? also once the car is wormed up ill have afew pics on ware she is leaking from the exhaust.
