Chevrolet Repair: 1999 Chevy Suburban, chevy surburban, aftermarket air filter


Question
My 1999 Chevy Surburban began stalling out while driving over a month ago.
It has done it many times since we have used fuel cleaners, replaced intake
system, had it tuned etc... There is no common element about when it
happens I can be accelerating or decelerating. The lights start coming on on
dash no one in any particular order. Sometimes its the air bag light
sometimes the security light. I loses power steering etc... I have noticed the
clock changes time but works when I restart it. Someitmes the lights start
coming on but it doesn't stall out. Can  you help me out? Thank you Clueless

Answer
I would take a closer look at the air intake system. I assume you mean an aftermarket air filter/air cleaner?
Check for leaks. Check for excessive oil from getting on MAF sensor.

Other than that, check for codes, scan data, etc.

Check battery terminal connections, grounds, etc.
