Car jerks me around 1k-2k RPM..

[always_broken]

I do have a cracked front engine mount, but if anyone relates please confirm it.
But when I cruise let's say through a parking lot, if I give it any kind of throttle it feels like the engines gets gas, then it doesn't. So it jerks me around.

I do have 4 cels:
02 heater sensor malfunction
manifold differential pressure sensor malfunction
fuel trim malfunction
and I forgot the other one.


I tried a test, I gave it throttle and let it coast, no jerking. So it only happens when I step on the gas.

Fix the problems you have now, thw fuel trim malfunction is probly why it is bucking.

Why are you asking whats wrong with it when you have 5 check engine lights and a broken motor mount? Fix it before you worry about the bucking.

I'm pretty sure the o2 sensor isn't causing it to buck, because if that's out I just run rich. I did some reading and the fuel trim malfunction and that is also caused by the 02 sensor.

I was just seeing if someone had the bucking problem and would tell me, oh ya dude, I had that happen, it was my mount.

No the mount will cause the motor to shift and break axles.

The car having 5 check engine check lights will ensure that it will not run right and that you will break crap cause you dont wanna fix it.

I had a similar problem. It turned out to be my TPS out of adjustment. Scroll to the bottom of the page for instructions on how to test and adjust.

Of course, as everyone else has stated it may be multifactorial seeing as how have so many DTC's.

Let me know how it checks out.
