The car starts up and idles just fine. However, when I let up off the clutch, I have to give it quite a bit of gas to prevent it from stalling out in first and second gear. It really struggles, bucking back and forth at around 2.5k rpm in first gear, and occasionally at higher speeds, but not to a very noticeable degree. Fairly consistent problem, happening 9/10 times.

Hi Gearman,

Thank you for the donation.

Seems the problem is with the engine misfiring causing it to stall when taking off.

Were the spark plugs and related items checked?

Does engine idle correctly and smoothly without any load?
Does abrupt throttle opening at idle causes any hesitation or misfires?
