I have a 4 door '93 Ford Escort LX Wagon. Last year it started jerking when climbing hills and the shop told us we needed a new fuel pump. I took it for a second opinion and it turned out it needed a new filter or something in the front of the engine block. It ran fine for awhile, with just a little jerking left. We parked it all winter/summer and started driving it again this last month. It's jerking really bad in first and second. Once you get to third, it's better, unless you try to climb hills. It's almost like it's trying to get enough gas, and can't. Not sure it's the fuel pump, though sounds like it to me. It does do better if I rev it up a little before going to first, and then shift a little later, with higher RPMs. Ideas? (we did get a fuel pump to put in)

Re: Jerking while driving
If you park your vehicle for a long time, you run the risk of having contaminated fuel in the tank. This happened to a car my wife purchased, and it was the last thing I found. It proved to be the problem. What you need to do is remove the fuel from the tank and then have the tank flushed. Fill it with fresh fuel and replace the fuel filter.

Hi, When was the last tune-up done? Should be done every 30-45KM, or depending on what your owner's manual maintenance book states. 1. Spark plugs 2. Spark plug wires 3. Fuel Filter 4. Air filter 5. Oxygen Sensor
If these have recently been replaced then do you have Check Engine Light (CEL)? If so, you'll need to get that checked by a mechanic.
best advice is dont go 40mph in 5th gear... if you are going up a hill at 40mph in 5th gear i have no doubt that it is jerking, your putting too much stress on the engine. shift up to 4th or 3rd you will be fine. 5th gear is an overdrive gear. 55+mph
does it **** whike driving or just when ur changing gears?? do u have overdrive? going up a steep hill is going to be tough for a little motor anyway if u have o/d take it off overdrive before u start climbing the hill this will help u there if its some thing that just started happening let me know heres me email [removed by staff] if u feel comfortable plz email me here
If this is a manual transmission the clutch has burned out, it may need to be replaced, if you do not do your own mechanic work I would suggest that you take it to a good local repair shop and have them check it out. If this is an automatic I would still suggest the same, but the actual problem could be more complex. Hope this helps, let me know.
