91 gmc jimmy lacking power? 4.3 liter?

[Stan]

carbureted throttle body 6 cyl. use to want to do a wheelie down the street butt now it doesnt get up and go at all. smells like its rich or something, i can smell the fuel.
maybe its an oxy censor? i just replaced that and the distributor cap and now it runs smoother but with lack of torq the oxy censor i might have cross threaded but i dont see any smoke coming out of the whole where it screws in.
it was hard to take it out and put it back in maybe its just like that and i didnt cross thread but i want my power back.

i dont hot rod it but when you need to make a turn in to traffic going from a stand still to 55 mph you need power

Could be many things, start with checking your Jimmy for any DTC codes that my be causing you to have no power. The second is to replace the fuel filter and clean your throttle body with throttle body cleaner, also clean your EGR valve and inspect your vacuum lines.

Start with these simple things to do and keep me posted, be glad to get your Jimmy running like a hot rod again.
