Some issues with getting car running....

[Supra87T]

I've been trying to get my 87 Supra back in running order. I went through a couple of afm's trying to fix my code 31 and they were all bad. So I purchased a MAFT. I'm now getting code 31 and 32. Does this indicate a problem with the GM MAF or something else?

Also, I've set the TPS several times using the procedure in the TSRM. I know it's calibrated correctly, but I'm getting code 41 and 51. I've swapped it out with another TPS and get the same thing. Any ideas on where to go from here?

Thanks in advance....

How's your wiring?

it looks ok, i know the wiring to the maf is good for sure. just reran my own wiring instead of using old wires for afm. i know the tps is getting 5v from the ecu.

alright, checked the wiring. it seems i forgot to soldier e2 in with the maft and the ecu wires. that cleared up all the codes.

however, when running the car idles rough at about 500 - 600rpms. when driving it seems to cut out at about 2800 rpms in all gears and doesn't seems to have much power. if i let up on the gas it will climbed to higher rpm's. anybody experience anything similar?
