Thanks for the replies everyone!

Ok ill try to address everything..

First, I meant to say bank 1 sensor 2 (apologies) which my CEL is pulling P0141. I replaced the o2 sensor when I bought the truck and reset the light, but it returned shortly afterwards, going off and on sometimes. I’ve ignored this because I understand it monitors the efficiency of the cat converter, not the fuel/air ratio, thus ruling it out for my A/C surges.

Secondly, My EGR has the leak at the junction where the rear of the valve meets the pipe leading to the exhaust manifold. I didn’t assume this was the cause of the surges because when my a/c is off, my idle is normal and no surges at low speeds either. Wouldn’t the surges occur without the A/C on too if it was the EGR to blame? But, I going to take the valve off this weekend to fix the bolt issue, clean, and test the diaphragm to rule it out.

So, am I wrong to come back to the compressor as the culprit? I mean it acts just like uncharged system would, only it’s charged and when it cycles, it surges…

oh Greyfox – Yes, I completely understand if I don’t know how to do something, to not tinker with it. But, if I never take a step to learn how to do it myself (and not damage it), it won’t get fixed. That’s why I started teaching myself how to work on engines. A girls gotta start somewhere C8-)

Beefy – No, this has been occurring for almost a year (figured it wasn’t too detrimental to my engine, not very proud of that).
I will try recharging the system to see if that will help. I’m unable to get ahold of a manifold gauge set though.
Am I able to test the compressor somehow to see if that is failing?

Dreamer2355 – I have no symptoms of power steering issues from what I’ve noticed. My rpm’s stay put when my wheels are turned to the max if that says anything. But, I will check the switch and make sure. Also, the check engine light is on but only for my bank 2 o2 sensor that has a hole in the pipe next to it. As for leaks…..”Today”, I had a bolt break from the rear of my egr valve and It’s leaking exhaust so my idle is now constantly 1200+ rpm. I find this oddly ironic…
Hopefully I’ll get that fixed by the weekend.

Thanks for the help guys!
