Had a "check engine soon" light come on and had rough idle and no power brakes at low rpm.. Local shop removed/cleaned/replaced EGR valve and problem was cured, for about
300 miles and now it's back..I've googled it and got a lot of info on carbon buildup, etc. and want to pull it and clean it.. my problem is FINDING it...
My Chilton's manual shows it as a large, one piece unit on the rear of the intake manifold, under the cowl. But on our engine, it appears to be 2 units, slaved by vacuum hoses, on the driver side of the intake manifold... The front module looks like a solenoid, the rear looks like a diaphragm in an old fuel pump... Can anyone tell me which part is the one that gets carbon deposits?? (assuming that I actually found the EGR)
Thanks.. mac Mac
