Re: DTC help!
The mass airflow code could be a huge number of things, dirty maf, vacuum leak, leak in the air intake tube after the maf, fuse, bad ground.
The TCC code means that the PCM is detecting 12v all the time on the TCC brake switch line. It shouldnt keep the torque convertor from locking up since the PCM should ignore the brake switch functionality all toghether if either of the two codes for it are set. The torque convertor will just unlock below the set speed not when you hit the brakes. Can't imagine a bad fuse or ground could be causing this one.
The engine speed code is the same one that is always set in my swaps if the customer doesn't hook up a tach to the tach wire.
The TCC code and the engine speed code aren't aeven severe enough to set a check engine light. I would focus on the MAF code. If fuses and grounds are good get some MAF cleaner. Those things are notorious for getting dirty really easy.
