95 chevy 1500 4WD running issues when out side temp is over 50 degrees
Under 50 truck runs fine but over 50 and hwy speeds and accl. it coughs and
spits back through TB and dies. Restarts and idles fine hit the gas and I get a
cough and die. truck runs fine under 50 degrees. I replaced the fuel
pump,pump relay and both filters inline and the sock in the tank. The outside
temp has me scratching my head. Need a little help thank you.
