1995 T100 Runs rough after warming up
I have a 1995 T100 with an 3.4 and auto trans. It starts good and idles fine when cold it will even rev up pretty well (with out stumbling) but after it runs for a few minutes it starts to stumble bad when trying to rev the motor. It also won't start on it own either (got to give it some starting fluid). I have checked the coolant temp (for the ecu) and it ohms out fine, the TPS seems to be working ok, I cleared the various codes in it and the one that come back is the Camshaft sensor malfunction code. I went and replaced it but still having the same issues, for what ever reason i never checked the old sensor to see if it was good or not. Does the camshaft malfunction cover up another problem somewhere else. Any suggestions or questions regarding this would be appreciated.

When's the last time it's had spark plugs and cables, air cleaner changed? Check engine light on? Are you using any coolant? Have you checked intake tube and vacuum hoses for leaks? Have you cleaned the throttle body and IACV? Fuel filter ever been changed?
Go up to Tools, Advanced search and start looking. We have lots of great info on the 3.4's around here.

good question on the plugs and wires, I don't know. air cleaner is new, light is on now because of the camshaft sensor malfunctioning, I just replaced it today, still no difference. Fuel filter is new too, I haven't had the Throttle body off yet to clean it, just hit is with carb cleaner, and pulled the TPS to check for movement along with the ICS. vacumn hose seem ok. I'll have to search some more.
