Why does my Chevy 350 TBI bog on acceleration?

I have an older Chevy truck from the early 1990s. It has a 350 TBI under the hood, but recently, it’s started to be a bit sluggish when I hit the throttle. What would cause this type of problem?

Used from 1987 to 1995 the Chevy TBI (throttle body injection) wasn’t known to have too many issues. However, the longer you run any engine, the more problems may arise. Your Chevy 350 TBI may bog down on acceleration simply due to dirty fuel injectors, a bad fuel pump, or fuel plugs in need of replacing.

Checking out these issues should resolve the problem. But whether you can revive your current truck or you decide to buy a new model instead, make sure that you keep your Chevrolet insurance costs at a reasonable rate by using the Jerry app.
