Ok I have a 91 Camaro RS 305 tbi it runs great and fells stong for a 305 that is but when I try to power break it and get some RPMs to the motor off the line its seems to bogg down right after I let off the break. It feels quicker actually just punching it off the line. Does any one know how to fix this is it something to do with the tbi ? Any help is appriciated on how to maby fix this.

thanks logan

 

Got a vacuum guage?

 

yes we have a vacume gauge.

 

I would run a vacuum test on it. It sounds like a clogged exhaust, and if it seems like I'm saying that alot lately, I am, but it's getting to be that time of year in the northern and central US where we start seeing more of that, especially with all the cold weather and rain.
