I put it on and the car wont run right..At high RPM(like right before shifting) the car loses power and bucks. On the highway you dont really notice it, jsut going through the gears.
What in the world would cause that?
Ive just plegged the vacuum line and left the EGR on the TBI. Been driving it like that for a long time with no problems. Just a check engine light every blue moon.
Is it worth running a proper EGR valve? Thanks

ABSOLUTELY! EGR valves are different for different applications, you MUST get the one for your car! Just because they look the same and they fit, does not mean they work. I discovered that with my own car shortly after I got it a few years back - wound up dropping $90 on a new one.
