I'm stumped with my fathers 92 s10 blazer with the TBI 4.3. The truck will not start cold without holding your foot on the pedal. Once started, it will idle, but very low, sometimes, it may even stall if put into gear too quickly. Once completely warmed up, it will idle, but still low. Engine runs strong otherwise.

I did voltage checks with the TPS, checks out fine. Did meter tests with the IAC, those tests came out fine as well.

Checked for vacuum leaks and found none.

What else should I be checking?
