New injectors? Just cause it's not turbo'd doesn't mean they can't stick. Plenty of 1.8 injectors buzzing around. Including mine.

Wait, your CEL is flashing? On a '95? I've only seen this on OBDII cars, indicating a catalyst damaging misfire. EGR would explain your high NOx though, and a misfire would explain your HC which is through the fucking roof. Specifically a misfire from running super lean.

No, it comes on when I cruise, the diagnostic test says its the EGR.

I also forgot to state that the shop refused to do the test with the hood open or a fan going. I wonder if running the car with the hood closed is increasing intake temps and I wonder if they legally can open the hood to test it.

That's weird when I had my 90 done last week they did it with the hood open.

I have a brand new 94-96 magnaflow cat that I bought just for the sniffer.
It's sitting on a shelf in my garage now. Feel free to borrow it if yours is shot and you need one to pass.

Compression (1-4)
150psi, 150psi, 130psi, 150psi
I'm guessing the gauge is off because I seriously doubt 3 cylinders are not "evenly damaged". I'll compare on the turbo car in a couple hours after I "get my crunk on".

Leak #'s:
Harbor freight gauge fail.

Lol, time to post in the "HF: Win or fail thread"

I don't think a bad cylinder could get 130psi even on crappy gauge...could be wrong though.

You have a crappy idle and EGR problems....me thinks you should fix the EGR and go from there. You said you looked at the EGR but it sounds like it's sticking.
