Whole car shaking
 

So my car has been doing this ever since I got it, even after I did a whole head job and I am looking for every possibility before I start buying more parts.

This is a manual car but I am almost certain the transmission is not the problem.

First off the car idle is not consistent, it goes from 500 or so rpm to 900 rpm and back and forth continuously. Than the car will randomly start jolting real bad even at 1800 rpm especially when cruising at 35 or so. I can even be going 75 in 5th and feel it jolt a bit when I let off the power.

It use to have a code for random misfire but that went away after my head job. My thoughts are that is it still misfiring and that is causing the jolting but I am wondering if it could be anything else, it does it in every gear, clutch has only 5k miles on it or so.

The throttle also gets stuck if I every stall it or sometimes it just does it randomly and sits at 1500 rpm and than starts going up and down in the revs like idling.

Thanks in advance!

Sounds like a computer problem most likely in the wiring. Could be a sensor or two out. What other codes have set.

Is it something like this?

Very similar to that but it doesn't hesitate for a second. And no other codes pop up at all.

perhaps its not getting the fuel it needs. maybe a dirty injector or fuel rail might be clogged w/ old gunky fuel. the misfire could be caused by fuel cut

Re: Whole car shaking
 

How do I go about fixing that, injector cleaner?

Re: Whole car shaking
 

cant go wrong w/ buying new injectors but if you can find a shop that can bench blow the injectors that could save you some cash an might help

I'm having similar problem but I just put new injectors in.
