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.

 

its an 0BD0 1990 civic sedan 1.5

 

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...

i haven't tripped the ecu plug with a paper clip...

 

ok.. i got the same problem.. 2006 civic si.. the car was on a mini accident.. i fixed it.. changed the intake because the stock 1 was messed up... i had to buy the MAF sensor.. so i put it in... now it wont go over 3000 rpm with out the sensor connected.. when i connect the sensor the cars goes over 3000.. but shuts off... it wont stay on for more than 10 secs... i too it to auto zone.. the codes say the MAF and IAT is bad.. thats all.. but i bout the MAF brand new at the dealer.. what else could it be??

 

Jump your ecu and find what code its throwing.
