95 v6 4x4 sputtering bad

[alexdowns926]

When I first start the truck and drive it for 10 or 15 mins it run fine. But if I turn it off and let it sit for 5 or 10 mins and try to drive it, it starts sputtering bad, backfires and won't hardly pull itself. Ive already changed the spark pugs and cleaned the mass airflow sensor. Anybody have any ideas???

Sounds like you might have a leaky injector. How did the plugs look when you changed them? Any one plug look different than the rest?

It could also be a faulty engine coolant temperature sensor. Maybe try swapping it out and see if the problem goes away.
