Does anyone no why my 84 chevy k20 5.7 is running so sluggish
ask a tech to road test with you, that's not enough information.
see if you can define the problem, when i accellerate from a stop? when i am driving normally and step harder on the accellerator? after it warms up? everytime i leave a stoplight? It seems like it doesn't down shift? It's stuck on one forward gear? Get some more feel for the problem. It is aged enough, you may need an inspection for safety, brakes dragging, tune-up, etc.
