Hi - I hope somebody has an idea for my car problem. I live in Poland and drive a 5 door, stickshift Daewoo Lanos. For some time it's been jerking as I give it gas, mainly in 1st and 2nd gear or if I haven't driven it for a couple of days. Sometimes it's quite a violent motion. I took it to a mechanic here to check the universal joint. He said it was fine (but didn't offer any other advice or suggestions). I've added fuel injector cleaner at least twice as well as something to dry up any water in the tank (we don't always get the best gas here, although the octane level is higher.) Any other suggestions for what I should look at/do? Thanks!
