Question about 1997 Ford Escort
I have a 97 Escort, and I have noticed recently that it seems to have some hesitation when accelerating, only in low gears. It seems to quit when I get over 40 mph, but until I get there it has hesitation. I thought maybe it only did it while the AC was on, but that wasn't it. The air filter is clean, oil recently changed, and I have gone through several tanks of gas from various places thinking that maybe it had bad gas, but it does it no matter the gas comes from. Any suggestions?
I have had a problem similar. The car was running ruff and having low power on accerlations and then it started stalling at lights and stalling when I slowed down on highway traffic. It was a vacuum leak in the PVC elbow tube if you look at the picture it was in the first elbow on the top that was cracked that was causing the problems.

I have had the same problem.. in my case it was a vacuum leak.. I checked my "PCV" Valve and I went ahead and replaced that, that was cheap. the leak was coming out of the PCV elbow! it had cracked and melted a little from the heat of the engine. I replaced it and it fixed it..
also could be a fouled spark plug or wire, that happened to me too at another time.
I hope this helped you out.

I am having the same problem with mine. It hesitates in 2nd gear and seems to come out of it after it gets going. I had the maching put on it and he said it was the EGR Valve. Going to change that here soon. Please let me know if you find out something different on yours.

Did the EGR valve replacement fix your problem ?

SOURCE: hesitation at 40mph and 50 mph.
A pop and hesitation is likely a backfire. The hesitation around 40 and 50 would be in keeping with that theory. There are several reasons you might be getting backfires and hesitation. If your ECM is adjusting the engine to run too rich this could happen. Misfiring might be occuring. Timing could be out. But one of the most likely is a restricted exhaust, likely due to a plugged, damaged or worn out catalytic converter. In some cases the converter may be bad enough to be giving you some performance problems, but not yet quite bad enough to signal an error. A vacuum test can help confirm whether this is exhaust related.
