My 96 Chevy tahoe stalls when I start it unless I turn the key and let the beeping stops and then crank it, it starts right up. Sometimes when I'm at a light the rpms go up and down and wants to stall
Replace the fuel pump and spider had it scanned and mass flow
sensor came up. Replaced it, scanned it again and still comes up
and I think it's not workin. So my question is what should I do next
and can this be causing me problems?
Check the wiring going to the mass airflow sensor as well as the plug that plugs into the mass airflow sensor. You may have a bad connection. HTH. -Jim
If you could give the actual code (ex: p0303) that would help more. Most maf codes are from vacuum leaks or unmetered air entering the system. I've seen many maf codes, most end up being something else.
