Default Can't go over 4000rpm!!

Well... I attempted to clean my MAP sensor tonight. Well i pulled it out and it seemed to be fairly clean, at least compared to what it looked like when i pulled the TB and put an ATX tb on, that was all gummed up. So i took the map sensor and sprayed carb/Injector cleaner in it and let it soak for about 20 mins. Then i dumped it out and sprayed some more in it and took a couple Q-Tips and cleaned it out perdy good. Then i put it back on and i get a code 12 and code 14 CEL is on and it never was before and i step on it and it has ***** and then at 4000rpm it's like it hits a governor. It's weird...Any suggestions??? Did i ruin my MAP sensor by taking those Q tips and cleaning it out?? Thanks...

Nah, cuz the TPS is on the throttle body itself. The MAP is in the center of the intake manifold. And i was cruisin right before i did this, but i think the carb cleaner and scrubbin in there with the q-tips did a number n screwed it up because i'm getting a code 14 and that's low voltage from map sensor. So tomorrow i'm headin down to the local parts store to get one, and i pray to god they have one on hand because i gotta work at 4 in the afternoon [sm=scared09.gif]

Well i guess ya live n learn, lol. Yeah i called up Napa today and carquest and carquest wanted $93 for a new map sensor, and napa wanted $69, both still too expensive but i ordered the one from napa so it BETTER be here tomorrow. The car is still driveable n everything just can't go over 4k rpm that's no fun!!! lol.

Heh, let us know if it works.. That doesnt sound like a MAP sensor to me... sounds more like a TPS.. maybe incorrectly replaced?
