I pulled on this PT cruiser yesterday cause it was driving 20 mph on a 35 mph road.. right after the pull my check engine light kicked on and i pulled the code and it says its the MAP sensor.. I have a couple spare cylinder heads so i pulled the map off on of em and put it on. The car is still havinf issues like it lost power. and the check engine light is still on. The car has a surge of lost power in first gear so i just rev a 2 hundred higher to take off. My car idles fine and dosnt die at idle when i turn the car on aat first the idle drops but then is fine. should i just buy a new map sensor an kick the one off the spare cylinder headto the curb?.. what do yall think?
The answer is obvious however i would like some good opinions from people who have delt with this issue. I'm going to forsure buy a new MAP sensor tomorrow and keep yall updated. i also should say i cant take off fine but right when i take off the car losses slight power its like a surge of power loss i cant explain it so i just quicky reved higher at take off to get the car home I'm not driving the car right now haha its in my garage right now
i can**** take off fine but right when the cutch out and I'm going in first gear i get a power lose surge

I think maybe you blew off or damaged a vacuum line during your pass. I would run through all your vacuum lines, making sure theyre all perfect. Then I would actually test the map sensor (not just tossing other random and questionable map sensors at it....).
Or maybe the intake manifold gasket, throttle body gasket or MAP sensor O-ring....

When you get a check engine code that points to a sensor, it's not saying that the sensor is bad. I'm sure there was nothing wrong with the original MAP you had on. The engine code is just saying that your MAP sensor is reading pressures that are out of spec from what they should be. 9/10 you have a vacuum leak somewhere on the intake side. Less common, there's an electrical issue with the harness or you have to bad ground. If you actually believe it's a bad sensor, than test it! Get a multimeter or OBD2 scanner that reports live data and make sure it's showing that manifold pressure is changing with engine speed. Pressure goes up with the engine speed and vacuum goes down. Anyway, you probably just have a vacuum leak.

Actually it ended up being a wiring issue! The map was fine. I went to Pick N Pull and got the pig tail for my MAP off a OBD2A Integra LS harness & correctly soldered it on to my OBD2A integra LS harness. Thanks guys for the help i appreciate! It took me a while to find the disconnected wire because the disconnected piece was hiding. The reason i replaced the whole pig tail is i didn't have enough wire to work and would have had issues with length.. THANKS HONDA TECH FAM!
