240sx runs pretty badly, not misfiring tho

[cueno]

Hello to all you 240 lovers. today i join you and these amazing cars! I just bought a 93' 240sx hatchback and already had to fix the infamous timing chain rattle. (thanks to nico for all the help on that). Anyways, my dohc now shakes constantly, most noticable at idle, and can be felt through the shifter. It isn's missfiring but it doesn't seem to have the power it once did either. It may help to know that before this started happening I replaced a bad injector and my careless self forgot an o-ring, thus I ended up cranking over the engine with a full cylnder of gas to the point where it would not turn over anymore. course i fixed that, but now it faintly shakes, and has a faint ticking or clicking noises from the head. I dont really know what to do about this so any help is much apprecitated. Thank you

Also, i seem to be getting bad gas millage, and just to let you know, i have cleaned the aiv valve, but could it possible have anything to do with the erg????

i kind off had the same problem , what i did was played with the injectors by twisting them until i noticed a change.

In your case that might not be the problem but my intention is to help out.

You may have done more damage than you think. Hydraulic locking a cylinder is a big nono
