I need this fixed as soon as possible, and i've researched the issue and figured out the maf wiring is usually the culprit. I bought this car with this same circuit burnt and it was kinda fixed by jumping the circuit with solder (not the best job) and the car fired right up. What I need to stress is EVEN THO THE CAR RAN ON THE PATCHED ECU IT DID NOT RUN NEAR AS GOOD AS IT DID (for a short time) ON AN ECU THAT DID NOT HAVE A BURNT CIRCUIT. I would like to know why.

This ecu which I bought only lasted an hour when one hard bump in the road caused it to short on that same exact circuit. Im going to post pics and if anybody knows id like to find out what it goes too.

Part 2: Im also going to post pics of my maf wiring. Some of which rested up agaisnt the exhaust manifold and got a little crispy. I cut the sheath back and took a picture......my question is DOES THE BARE WIRE WRAPPED AROUND THE MAF WIRING CONTROL ANYTHING?, also I took a pic of the wiring where it looks like someone patched the harness in, and I would like to know if these wire colors are correct.

Thanks in advance for any help.
