Map pressure I just got a scan tool that gives a live feed and noticed a few odd things. Ignition advance at idle is 21-21.5 I thought that was a lot map sensor reads 31-32 kpa ~9.4"hg and tps never goes below .4%
Are these normal for a 00 ls1 only mods are full exhaust car doesn't have egr or air no lean code just both rear o2 sensors have high voltage even though I don't have rear o2 sensors
I also get a random low idle. ~400-500 rpm. Idle is usually around 800 unless the vehicle is moving then it's around 1000-1100.
