Hi! I've been wrestling with this problem for a while, car runs pretty good but idle is not good, RPM humping between 650-750 sometimes 750-900 and sputting from exhaust irregularly, bank 1 in, bank 2 out. parts already changed is: plugs, wires, coils, fuel pressure regulator, injectors, O2 sensors, heads compression tested, timing checked, tried to locate if there's any vacuum leaks without success(only hissing noise i hear a ten seconds is from somewhere near ABS pack after i shut engine off), clean TPS, clean ICM and tried PCV delete plate. Any change making no difference and running out of ideas..?
I drove car to emission test the other day and the test guy's opinion was the car was fine, but is it. What do you guys think from these values?>>>
at idle:
Co% 0,02%
Co2 14,10
HC 16
O2 0,70
Lambda 1,069
With revs:
Co% 0,04%
Co2 14,20
HC 16
O2 0,40
Lambda 1,016
ShortFT1 0,0%
ShortFT2 -1,6%
LongFT1 -12,5%
LongFT2 -8,6%
