1991 Escort LX 1.9 Getting 27mpg
So I did a search for "Code 33" and got a result for every post made on 33 mins past the hour.
So....according to my code reader, when I do a key on/engine off and a key on/Engine on, im getting a code 33. The book states that is a faulty EGR valve. Does this sound correct to any all that might have experienced this before? Thanks to all that comment.

dont worry about all your egr valve does is not make big cities smog filled

if it does bother you take it out and let it soak in carb cleaner

I'm guessing your car is Cali emissions right since it is a '91 with egr? My car is a '96 and I had a fit with the egr. Once I fixed it my mileage went up half a mile per gallon. I replaced the dpfe, then the vacuum solenoid, and finally got tired of it and replaced the valve itself. Along the way I also replaced vacuum hose. In my case it was the valve that fixed the problem.
