So here's what I have got going.

89 chevy r2500 suburban 3/4ton 454 v8 4x4 upgrade

Last week while driving the truck lost power. At first thought it was the fuel pump, but once I got the truck towed to the house, I found that the dual pump was working. And that I wasn't getting spark, so I replaced the coil, spark plugs, spark plug wires, distributor cap, and she started running again. But a day after I got her going I was driving on the interstate and she just wouldn't accelerate. So since then from reason fb forums it appears to be a sensor issue. So I have replaced the map sensor and engine temperature sensor. She was having a lot of troubles starting up and after I replaced the sensors she fired up just fine. But I still have the acceleration problem. Has anyone ran into this or can point me in the right direction?
I am not very mechanically inclined and can't afford a mechanic, so any help would be greatly appreciated.

Thank you!
