Car jerking while accelerating.

Hi guys,

So recently my car has been having issues where while i'm accelerating if i lightly tap the gas pedal the car will jerk pretty hard back and forth. It happens a lot (not all the time) at higher speeds say at 60 k/m and up, but some times even at low speeds. I've tried changing the spark plugs, coils, engine mounts (top, rear strut mount). the vehicle is at 135,000 km. it's a 2012 1.6 CVT. Hopefully someone can shed some light on this issue.

Can you recreate the problem while in neutral? It might help with trying to figure out if it's an engine problem or a transmission problem.
Also note the RPM's when it happens again.

I would also check the transmission fluid: Level, color, and feel (rub your fingers together, check for slickness)

Hey guys, im the OP. Forgot my password and the forumn doesn't reset ur password for some reason.

After spending hundreds of dollars on this car I finally figured it out.

So, I tested if it did the same thing while in park and neutral and unfortunately it did. So I went back to the basis of the problem, which started with the spark plugs, after i checked all the spark plugs and replaced them, as i was putting everything back together it had me thinking. It would happen everytime i lightly tap the gas so im assuming it had something to do with the MAF sensor or the MAF itself. After checking the sensor i found out the connector that had a plastic clip was broken. So I put on the MAF connector on loosely and took it for a drive, this time it had the same issue but was even worse, so when i pushed it in tightly and test drove it, i discovered the issue had been resolved. Looks like I have to replace the connector. Anyways hopefully this will shed the light on anyone else that is having a similar issue, check the harness first, before replacing a bunch of other things on ur car.

Thanks for the update. How the MAF connector got broken in the first place? By itself?
