My corolla jerks and bucks at low speeds - Toyota Nation Forum : Toyota Car and Truck Forums

Hello everyone:

I have a 1998 corolla, manual transmission, with 200,000 km on it. I've had a problem with it for a long time and never was able to repair it completely. When going at very low speeds, the car starts shuddering and jerking back and forth. The problem is evident when I take my foot off the gas pedal then try to accelerate again. If I do this slowly, I don't notice this problem as much. Then engine also runs smoothly when going at high speeds. I have got the carb checked and had it repaired; the problem seemded to go away after that for a couple of weeks then it started coming slowly. I then purchased a new carb and put it in, and again, it ran nicely for a couple of weeks then the problem came back. Because the carb is a little expensive, I want to make sure that it is the source of the problem before I go ahead and replace it. I would be very thankful for your help.

Does your car really have a carburetor? Or is it the "throttle body" that was replaced?

If you mean by "throttle body" fuel injection system, then no; my car has a carb.

In 1998 all corollas were fuel injected no carb there like said before, it sounds like fuel delivery check the fuel filter and injectors for dirt

Sounds like a worn out distrubutor.

He is in Saudi Arabia. His filters are probably full of sand.

And since the 98 doesnt have a carb he might mean an 89.

Though I have had my car's carb repaired and replaced before, you made me doubt if my car realy had a carb. On my way back from work today, I passed by a mechanic and he confirmed that it has a carb! My car is 1998 all right, but I believe the engine might be different over here in Saudi Arabia. My car looks the same as the one below. Any ideas?
