my 97 honda civic ex is jerking?

Check your fuel pump and fuel pump relay if working properly.

Sounds strangely familiar to a recurring dream I have....blowing up import motors for fun. There's a ton of interesting ways to send it on it's way. You need to decide if you want catastrophic failure at idle or while the vehicle is moving. I'd imagine you'd rather do it while sitting still and avoid any problems on the road and a long walk home. If you want to go for an elongated meltdown drain it down to about a quart of oil. Rev it up to near redline and within several minutes you'll hear the friction, a few more minutes and it should stop dead in it's tracks. You could also drain the coolant and let the head crack...this would produce some pretty interesting effects (lots of steam). Dropping needle bearings into the intake would produce some really catastrophic failure pretty quickly....along with a vast array of interesting sounds. The options are limitless really. It would be more fun to destroy while driving. Drop it into first gear and run it WOT (wide open throttle) for a few minutes, it will most likely throw a rod...maybe even put a dent in the hood. The stress on the motor while in gear will give it that extra oomph it needs to fail. Good luck...have fun and be safe!

higher mileage honda's are prone to plug wire failure,remove the plug wires from the spark plugs and check them for carbon tracks,or holes burnt through the wires.if your brave pull the wires up one at a time while the car is running and see if a spark is coming out of the plug wire to ground,do not touch or lean on the car while doing this or you will get a 50000 volt jolt you wont soon forget.

well need symptoms of motor operation but i can guess that its the idle air control valve which all you have to do is clean it (usually) but for it to be this whenever you are sitting still motor will rev up and down and when you drive try to gas it and if it smoothes out when you accelerate hard thats the problem

i take it its automatic if it is u mind need to change the injectors or try using a different gas like octane 91

let it keep jerking and finish its thing' itll stop once its done
