Default Car bucks and spits rich, stalls only when it warms up

Hi - i've been trying to fix this myself for the last couple of days but find that i've run out of knowledge (i'm surprised it took this long...)

the trusty-t (86 T-Type, oem ecu, inj, chip, turbo, maf, 3"dp and dual ex) just started to do this on the way to the boys football games on Saturday. it fired up great, drove down the road fine and then 1/2 way to the field, as i started to drive away from a stop light, it layed down and coughed, i stood on it a little and it picked up to 60k, and cruised fine, then as i got closer to the field, and i had to slow down, it wouldn't accelerate again, just coughing and puking, running really rich, then stalling. i let it cool down a bit and it started and ran like crap, stalling all the way home. i had to bring the mini-van to football...the boys were not happy!!

i changed the ign module and that didn't do anything, i disconnected the battery and that did nothing. i changed FPR's, played with the fuel pressure-still nothing. no bad connections, no vacuum leaks

Help! I've spoiled my boys-they only like to go to football in the Buick!!!

Matt

Do you have a spare MAF you can try?

Plug(s) take a crap? Ignition wire(s)?

I think Sean hit it, check the mAF. Plugs and wires maybe affected by the MAF going bad. Also when doing a module or coil, I recommend doing both as a unit, especially if they are original.

I don't have a spare MAF. i did check the connection on it, but thats about it. i took it out recently and cleaned it out a bit - maybe i damaged something?? i'll call around today and see if i can get one locally. i'll change the plugs while i'm at it, any specifics there i should buy NGK, delco?

thanks!
