1992 chevy subrban engine 5.0 keeps on stalling out on me. it is in a 1990 chevy stepside. I have replaced the fuel fitter and my map sensor.I need to know is there anything else I should be checking for??

My 95 sierra started doing that when i plugged a new o2 sensor in ..last owner didnt have it plugged in so i put a new one in and it started stalling and bogging out while idling in gear then it would just die...i unplugged the o2 sensor then everything went back to normal im still trying to figure it out ..but for sure runs better witout the 02 sensor mine is the 3 wire sensor..

Try cleaning the egr valve and the idle air control valve

have you checked the fuel pressure on the rail

+1 on the IAC

when dose it stall out at idle or coming to a stop or just out of no where dose it go away when hot

check fuel pressure at TB is it equipped with a throttle position sensor some times they can mess every thing up
