87 k5 350 5.7 L surgeing
 

re cap on things done. cleaned fuel system rebult tbi new tps,dis., module,knock,o2,wires,plugs,cap,roter,egr is caped off. it will die once in a wile it will surge once in a wile seames to lack power. when i take off slow is when it surges most. some times when i take off she seames ok then she felles like she gets a boost of power. so i know she has more to give I just dont know what the prob is I am sooo lost.

Egr is capped off.... on a stock 87 Tbi motor? did you get a chip burned or something for the ECM when you did this? just curious.. i know my 87.. and 88 didnt like my Egr being capped off so i have them on my trucks again..

hope this helps
