TRUCK RUNS LIKE CRAP WHEN WARMED UP?
MY 91 CHEV 1500 RUNS LIKE CRAP WHEN IT REACHES OPERATING TEMP. I HAVE REPLACED MY PLUGS,WIRES ,CAP, ROTOR, IGNITION P/U, IGNITION MODULE
AND THE DISTRIBUTOR SHAFT , IVE SET MY TIMING TO 0 DEG LIKE THE STICKER SAYS UNDER THE HOOD. ONCE IT WARMS UP I HAVE NO POWER AND CANNOT REACH
100KMH ON THE HIWAY EVEN AND MY FUEL MILAGE SUCKS. WHAT ELESE CAN I DO?

You didn't say if you've had a check engine light or anything, but it does sound like a sensor problem, either O2 or temperature. Autozone (if you have one nearby) will read the codes for you for free and that might point you in the right direction. You could have a code stored even if you haven't gotten the check engine light. I had similar problem on an old Caddy once and it turned out the pick up coil was turned very slightly out of position. Let us know what you find.

WILLI --- Define "runs like crap". Does it miss? or bog? Or does it run basicly smooth, but just does'nt have any power? If the later is the case you might have a clogged cat.

did u disconnect the wire from under the dash (passenger side) before u set the timing? this will cause your timing to b retarded if u didn't (loss of power).
