My car boggs at 1500 to 2000
rpms, it is really annoying now when releasing the clutch when I am in
first gear to get going it boggs.. I
think it is the EGR valve doing this, when I raise the idle it boggs
but when I disconnect the vacuum line from the EGR it is fine. And when
I raise the idle with the hose disconnected it is fine but when I
connect the hose while the idle is up, it boggs and runs rough..I tried
this with another EGR valve I got from the junkyard and does the same
thing, I cleaned out both EGR valves and the diaphram moves and down. I
also replaced the EGR solenoid. There is vacuum from the solenoid when
I raise the throttle, so the solenoid is good.Is my EGR valve
bad? I do not see how the valve can be bad, is there something internal
that could be bad? The diaphram moves easy, so I think it is good, but
when it is on the car connected it boggs at 1500 rpms..I just do not
want to buy a new EGR valve and the bogging still happens..Driving the
car like this is really annoying..What do you guys think?

Before buying a new egr concider that the problem might not be the valuve itself. could be senosrs sending bad info to the computer. hook up a reader (or go to auto zone and let them do it) check the code erors. itcould be the ects sonsor or somthin simple.

 

A) What year and model? Vacuum actuated EGR sounds early 90''s....

B) +1 on the ECTS. Especially if it has never been replaced. Replace connector when replacing sensor (just DO IT)
