I have a 95 T 100 with the V6 in it. The problem is after it gets warm it runs very rough when any gas is applied. when at an idle it runs perfect. Also when it is cold it starts and runs fine, as it warms up you have to keep letting up on the gas to keep it from running rough, almost like when you had points floating on older engines. also now after it gets warm it won't restart with out a sniff of starting fluid. anyone have any thoughts on this problem?
Check the vacuum lines for fuel. There is one that can suck Power steering fluid in the engine when warm. Also I check the one that goes to the fuel pressure regulator it too can leak and cause fuel to be sucked in.
That is what happened to me. Try cleaning everything listed before and the IAC, Throttle Body and MAF. Whens the last time you did any service to your truck such as the spark plug, wire and fuel filter?
