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.
