Long story short: Lemons race 87 mustang w/ 87 TC power. Yellow wire (I think) to VAM was cut by alternator pulley. Car ran like crap until we found it. Ran for about 4 hours sputtering ans backfiring. I'm hoping we were using too much fuel, rather than not enough.
Thoughts?

No yellow wire going to the VAM. Was it a thick (10 ga) yellow wire?
PCM reverts to a sort of lambda N mode for fuel control with inop VAM, depending on TPS and RPM. Usually idles OK, and runs rich for safety. Without the VAM it will run like crap under boost, and often go lean.

I was in the car in my 6 point belts. I do think it was a heavy gauge wire though.
So we were running lean for 4 hours or so???
Lots of sputtering and popping...
