Last two weeks, my 95 Mercury Villager (79,000 miles) is displaying Check Engine Light on. This typically happens when I am driving up a mild uphill slope at highway speed (above 55 mph). Mostly the light disappears at the end of the slope, or if I slow down. The check engine light never shows up in city driving, or on level highways. I got a mechanic look under the hood. The EGR/BPT hose is fine. Fuel pressure pump, gas cap, crankshaft, timing belts are okay (these are the usual suspects). Before heading to the dealer, is there anything else that I could look into ? Does the fact that this light shows up only on uphill at highway speed give any clues ?
