Re: EGR Valve
My motor is the 91 2.8 litre V6, it has more power in the higher gears now, definatly 5th gear(i have the manual), or at least it seems like it to me, if you have a 4.3 i wouldnt worry about it. Im not sure how the mechanic made it stay closed. The Service Engine Soon light only comes on after like 8 miles or so of easy driving then it goes off if i shut the motor off for awhile. To my understanding from the guys on the Fullsize GM boards the EGR helps exhaust efficency or something like that by rerouting the exhaust through the motor again if there us unburned fuel in it or something to that sort. We talked about this with my Deisel motors in febuary i think. If you guys live in a emissions testing area, i wouldnt do it becuase the mechanic told me it would run normal like this, but it would never pass and emissions test this way. IF you need anything else, im a regular on the SFA board and IFS board, or PM me, i try to stop in hear everyday or two.
Also im not sure if its Vacume Or Electrical
