EGR Valves

(Exhaust Gas Recirculation)

When these are bad, they usually give a vacuum leak which results in a rough idle. We have not done any of the '80's for a while, but are doing a lot of the '86-88 non-turbo's. These are buried under the intake manifolding - so we always check them if we are down there for any reason. Here in California, the car can not pass the smog test if the valve is not working.

Air Control Valve
Large back-fire on deceleration and/or between shifts usually means this valve is "no good" especially on 79 & 80 RX7's.
Also, if the car will not pass an emissions test, this is the culprit 90% of the time. If your O2 reading is less than .5% and HC and/or CO is high, this is your problem.
