what could have made my ecu do this?
Look in the red circle, hard to see but that piece and the board around it are fried.
http://img139.imageshack.us/img139/3483/ericzi4.jpg it says Q31 to the left and R135 to the bottom.... aside from my ecu being fucked how do I know this won't happen to me if i plug in a sweet virgin p28? Also anyone have any obd1 ecus for sale? Anything cheap? |

isnt it worth the 50 cents to try to fix it? otherwise you can get a po6 from the junkyard and convert it for like $30.

But if your ecu runs fine, there isn't really a big need to replace that part unless you really want to. Just make sure that you have the plugs right in the engine bay. |

Q31 is PCS (purge control solenoid)
No need for one on a HMT car anywho...as long as it didnt take out the rest of the board, boost away! |
