Car Forum / Ford / Ford Cars / November 200494 Ford Escort bucks
I've got a 1994 Ford Escort with 132k miles on it. It has had regular and preventative maintenance. In the past few months, I noticed that mostly during accelleration, the car bucks, but will occassionally not do this. I replaced the oxygen sensor when this first started at about 129K miles (it had never been replaced up to this point). Any hints as to the cause/cure? Specs: 1994 Ford Escort Pony, manual transmission, 1.9L, 132K miles Thanks, Jed > I've got a 1994 Ford Escort with 132k miles on it. It has had regular > and preventative maintenance.

Any change there since before this problem? Should start in about 2 seconds without touching accelerator Have you changed the fuel filter? WHY did you change the oxygen sensor? > ANY other symptoms? > [quoted text clipped - 7 lines] > > WHY did you change the oxygen sensor? No other symptoms that I've noticed. Accelleration, cold/hot start is the same as it has always been. Runs/idles well. No other problems noticed. Fuel filter changed about 10k ago. o2 sensor changed because a previous Google post referred to the o2 sensor going bad and causing bucking. Changing it also seemed to lessen the bucking, but alas, it continues... I have a '95 Escort with 176,000. At about 130,000 it had a hiccup. Would idle fine and would go up to 35 or 40 fine also. When asked to climb a hill or get on the highway, it would buck and hiccup. Turned out to be the ignition coil. My '95 has a distributorless ignition, as I think yours does. The coil is right on top and easy to get to. It's actually two coils packaged together. It was about $43 at Advance Auto. It would be a good idea to change plugs and wires now too. Scott Ssaund9084@aol.com Have you checked your TPS yet? I have the exact same problem with a manual 94 LX wagon with about 145 k on it. Have you tried any of the remedies listed here? Any of them work? Thanks! > I have the exact same problem with a manual 94 LX wagon with about 145 k on > it. Have you tried any of the remedies listed here? Any of them work? > > Thanks! Sorry for the delay in replying to your post. I've had the fuel filter changed which seemed to lessen the bucking - then I tried "SeaFoam" fuel system cleaner (available at Napa Auto Parts amongst other auto stores) and it seemed to lessen it even more. I've only gone through 1/2 tank of gas since I tried the cleaner, so maybe it'll get better with time... Next stop will be to replace spark plugs/wires... Thanks again, Jeff I haven't been able to read the whole thread here, only the replies. I had a hiccuping problem with my '95 escort. Wouldn't even climb a steep hill for a while. Turned out to be the ignition coil. Had replaced the plugs and wires first. Coil was about $43 at Advance Auto.

It seemed to be the parking brake was not disengaging. I had that serviced a few times and each time the problem would go away for several months (or even a year or more). It didn't have nearly as many miles, though. -D  SignatureLove is not affectionate feeling, but a steady wish for the loved person's ultimate good as far as it can be obtained. --C.S.
