1994 1500 hard starting, stumble off idle, hesitation at light throttle

You're welcome Dan, and thank you for letting us know what fixed it.

On the these TBI trucks the magnet that induces a voltage on the pickup coil is actually part of the distributor shaft. Gm does sell the shaft by itself but I got sticker shock when a friend of mine told me what he paid for a shaft at the local dealer.

Many of the various brands of aftermarket distributors are having modules failure very soon after they are installed. If you have any problems soon, have the new module tested.

Many auto parts stores in my area will test the distributor module for free if you bring it in.

Make sure when you install or reinstall the distributor module that you use heat sink compound under it. The compound helps dissipate heat from the module. Without it, the module will fail.

Glad you got it fixed.
