i need some help :( Options

[halotalo]

so ive bought a car that ended up being a total bust on me ( had to rebuild engine so i replaced clutch and various other thigs and catalyticconverter)

and my problem is that when i hold down the gas i get mini shakes every few seconds. especially going up hills. it also at random times speeds up a lot more like it gained a few more hp lol. ive also noticed it idles high while cold until it warms up.

now im thinking it could be a bad tps, or maybe fuel pump?


its a 94 gt
