so, Ive had an issue with my ze since i dropped it in about 9 months ago. I can seem to get it to idle anywhere near 700RPM, usually its at about 1200RPM and randomly, it will idle at 700RPM until i drive it to the next light and then it will idle at whatever it likes. The other issue is that when the motor is fully warm or after Ive given it a bit of s---, it rev's up and down between 1000RPM and about 1500 RPM. As soon as it hits 1500RPM it drops to 800RPM and repeats itself. The only way i can get it to idle is if i press the gas peddle multiple time, but as soon as i stop, i returns to searching for idle.
Here's what I've tried:
Different throttle-body (including TPS sensor)
looked for vacuum leaks
changed CAI (in-case of possible leaks)
played with the idler screw ( i can screw it completely closed and the car does the same thing or will rev higher if i un-screw it)
Specs:
96 MX-3 GS OBDII
KLZE w/ K31 Cams
CAI
Pacesetters
2.5" SS mandrel bent
no ignition mods
Throttle body coolant bypassed
engine codes :
EGR codes associated with no EGR equipment hooked up
sometimes MAP / BARO code but very rarely

any help would be greatly appreciated
