When my car is cold idle is 700rpm...when car warms up after 5 min of driving idle fluctuates 900-1000 and sits after a few tries at 900 and hesitatesd..aslo the engine will make a rattling sound???Car will aslo jerk when deceling in 1st below 1700 rpms? Compression is inconsistent and I loose a bit of coolant slowly without any leaks?
(cleaned iacv, calibrated tps and cleaned throttle body)

No code and I have cleaned it and the throttle body to...no luck

hows your valve lash?

by "compression being inconsistent" what do you mean? do you mean 5-10psi off or more?? post numbers of your compression readings.

 

I just got the comp. checked and all 4 where at 180 or so...so that's good...it's more a inconsistent throttle response I guess.....I have alot of slpiced wires running so it could be a resistence proble cause my tps is calibrated!!

Thanks
