1992 Buick Regal stalling, suuging and chugging issues

[bandanaman]

It happens a couple minutes after starting, if I go in reverse or drive sometimes it'll stall out with out my foot on the gas. I changed plugs, wires, map sensor egr valve gasket, cleaned throttle body iac and egr, fuel pressure was normal, cant find vacuum leaks. Does anybody have an idea or have had this problem before? map sensor reads bad but I replaced it and tested the new one, code 33 is coming up, I used a multi meter at the plug and its getting 5 volts. Here's a video.

Was it revving by itself in the video? Hmmm...what's your fuel pressure doing?

bandanaman, I have the exact same problem. Have you ever solved this issue?

Check resistance of the injectors. Should be about 12 ohms, if it's less, replace it.
