car jerking at low rpms

jeffpanya · Feb 20, 2011

just started doing this, I'll start from a red light and give it some gas and as it hits 1500 rpms it does a little jerk and after that its fine, it happens in all gears, anyone know why ?

5spd btw

I think my car is doing the same thing....Ever find anything out?

sounds like ur clutch going out... i'm no expert, but it sounds like it...

still have not found anything was told could be a vacuum leak, idk, the clutch has been replaced about a year ago, clutch still grabs good doesnt slip

Rear motor mount? It's solid and not hydraulic like autotragics vacuum assisted motor mount. It could be broken. Check the front for stress cracks from it moving so much? Why do they say a vacuum leak? There are like 2 vacuum lines on our 5spds.

i know one of the motor mounts are bad, the code was a p0240 ? i think something to do with o2 sensors and catalytic converter i have a magnaflow hi flow no res and muffler, i changed the cat last year.

I have a similar problem. It shudders a couple times then goes away at higher RPMs. One of my friend's asked if my clutch was slipping. I hope that's not the case because that is money I don't have. Haha.

Any other input would be great.

To test the clutch get up to about 20mph, put the car in 5th gear and hammer the gas. If the RPM's rev up and the car doesn't move much, the cluth is (going) out. If it bogs/slowly accelerates then your clutch is fine.

I think you mean p0420 since p0240 is not a code.

code #1
P0420
Catalyst efficiency below threshold (bank 1)
Explanation:
The oxygen sensors monitor the catalytic converters ability to store oxygen

Lots of info here

Eh, i wouldnt recommend smashing the gas in a high gear, its not really good for the car.

Instead put the car in 3rd gear from a stop, if u can accelerate off the line in 3rd then ur clutch is out.

But i know its more of an engine problem because ur bucking at the same rpms everytime in every gear.

thanks for the info now i just gotta figure it out, changing plugs caps

thanks for the info, i just gotta figure what it is now, im going to change spark plugs wires etc whenever its warmer here.

the clutch is fine, it does squeak but pretty sure its normal, might just need a tune up, especially if im going uphill it will just seem like its bogging down :crazyrun:
