Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
At warm up idle rpms are around 700, I turn the ac on and it goes to around 860 and whenthe compressor disengages it goes back down around 720 or so.
The stutter only occurs bad when at a stop light with the ac on. The car jerks a little and the rpms go down under 500 and then back up to 800 or so. Feels like the car is going to die then it revs itself back up. I have noticed at night time when it does it you can see the interior lights flicker when it starts to stutter. When taking off from a stop light the car kinda jerks and then starts to go, but soon as you get going the power is there. Just started noticing it the past couple months since the ac had to be turned. No problems with heater or regular air.
No ac works perfect and blows very cold air. I cant hear any noises coming from the compressor.
No adjustments on the the throttle body at all. Any way to check load on the compressor?
Yeah, steps to do that
Ok got a few numbers for you. These numbers are with ac on and off sitting at warm idle, all accessories off.
AC OFF AC ON
Calculated Load - 17.3% 26.3%
MAF 0.27 Lb/m 0.53
MAP 8.0 Hg 11.2 IAT 131 deg 129
IGN ADV 7.0 10.0
Voltage 14.14 14.08

No its not that I depth
I turned that screw half turn in and drove it today, still no change. I did a live data stream while driving. In Park the car idles at 860-880 with the ac on and when i put it in drive it goes down around 698-710 and when im at a stop light it sits around 710 then down to around 500 when it feels like it is going to die.
I wasn't listening for the compressor but will do another drive and let you know.
I have had the car for a couple years and I haven't touched the timing belt at all, the car does have 160k on it, so not sure if timing has ever been done.
