Acceleration jerking

[PavelTol]

Hello, guys, here's a problem: while accelerating hard at 1st and at 2nd there is some jerking. What can that be?
The car is stock, with no mods. Yesterday had my right engine mount (passenger's side) replaced by the new one. Spark plugs are new.
Could that be clutch not engaging completely?
Thank you!

hmmm was it replaced by the dealer?? if so take it back especailly if the work was done under warrenty. Did this ever occur before the mount was replaced?? if you yourself replaced it check and make sure it was done correctly and that all of the bolts are torque'd to spec.

yes, the work was done under warranty, approx 10k miles ago

Mine has done this but not often.. If I cruise in 2nd I notice it will surge back and forth if I hold the gas pedal steady. But I noticed in 4th if I give it some gas at a lower rpm it will hesitate and surge but it does not do it all the time

sounds like the stutter so many of us suffer from, I get mine in 2nd and 3rd...did the coil stretch and it went away for a little while.
But its back for good now it seems.
