My car jerks on second gear when I slow down while on second gear and then want to accelerate back. After changing the plugs and air filter it got a bit better but after driving 500+ miles it is back to the same point.
It is a manual transmission carburetor Suzuki Swift 1996, the saloon model. The idle RPM is set to 0.7 to 0.9k. Got the butterfly valve repaired as well (I think this is responsible for uneven gas intake?).
Failing to understand, what could cause this?
Explaining the jerks:
It jerks like sudden continuous thrusts, no knocking sound from engine like when you under gear. The more I press the gas the more jerky it gets, so i release the gas, press the clutch and then time them both to accelerate, as what you do in a pick-up while starting off the car from stop in first gear.
