check engine light is on and wont go over 3000 rpm
 

i recently changed my tranny, and everything worked fine until about 2 mins after its on the check engine light comes on and it runs like crap(wont go over 3000 rpm), i made sure all of my connections are plugged in about 50 times. a buddy of mine says it could be my map sensor and i called a couple of mechanics and they all said the same thing. and i also heard that theres a way to jump some wire to give me a code to tell me exactaly whats wrong with it, but i dont know how to do that either, can anyone give me advice???

Did you re-connect the ground wire that mounts to the tranny casing when reinstalling your trans ?


what year is your vehicle?

Well is your CEL coming on? If you don't know how to pull the codes, run a quick search of the archives.

If your car is OBD-II (96 or newer) you can go to Auto Zone and they will hook in for free and tell you what the error is.

Check your grounds especially, the one on the thermostat housing. I have seen this many times before. Also pull up your carpet and see which code it is throwing. Make sure if you do find a loose or disconnected ground that you reset your ECU

bump bump any new developments? would help me out a lot... similar problem.. almost exact.. wrong p28 chip i think...

Jump your ecu and find what code its throwing.
