92 Ford Tempo ERG valve trouble

Home  \  Repairs & Maintenance  \  92 Ford Tempo ERG valve trouble

My 94 Temp has had several sensor problems (mass flow reg, O2 sensor)..that I have fixed and or addressed with members comments, thanks.
Ad today this problem came up today. History: 134,000 miles 94 Tempo 2.3L. Major tune up at 100,000 miles. Now when car runs around 5-6 minutes AND gets up to say 55-60 MPH..the 'Service Engine Soon' yellow light comes on and stays on. Car runs great, just the light stays on. When I turn off car, the light goes off until I get it up to around 55-60mph. (NOTE it is very cold here in Louisville this week, 0-10 deg). All fluids, oil are in good conditon. NOW I get a code reading that indicated ERG valve problems..that is the only code that came came out.

Question: What happens if I do not replace the ERG valve.?

Thanks, fanman

well in california, that would fail smog checks. u should test egr first b4 replacing, apply vacuum to egr and see if it can kill engine at idle, then check for vacuum source by flipping throttle real quick.
