1994 Chevy C1500 hesitates

Post by Garden.Guru »

Hi.
I purchased a used 1994 Chevy C1500 Extended Cab Pickup and have replaced sparkplugs, wires, distributor, MAP sensor, Fuel Pump, & other items but the truck still hesitates when I start to accelerate or go up a hill, especially after it warms up.

I purchased an OBD1 reader/scanner to Laptop Cable and have installed the Tuner.net program but have no idea what to do to diagnose problems. I would appreciate any advice or suggestions on tutorials or manuals that might help. :?:

Thanks
