how much of a difference will a new egr valve work?

the one thats on the truck is plugged shut with crap.. how much better will it run if at all any better???

should run better. how old is the truck? do you really need it

HUGE!!! LOL if its pluged then your truck should be running ruff and have crappy throtal response. you need to fix that asap. incase you didnt know your egr recirculats some of your exhust back into the intake to help cool combustion when needed. when that starts to malfunction or gets pluged thats when youll notice your truck running ruff.

it is a 1990 chevy with 350 with tbi. it has always had really bad throtal response. at idle the exhaust always sounded weard sounds like a tractor from behind at idle.
