240sx engine shakes/sounds like motorcycle

[dennydizzo]

i've been driving my car for about 20 mins to get something to eat then drove it bak home i noticed my car didnt want to accelerate and engine/shifter shakes pretty hard plus car sounds like a motorcycle when acclerating...once i hit about 3k rpm it drives somewhat normally how it should and but still sounds like a motorcycle..

once i got home i checked and didnt see anything out of the ordinary in the engine but found sprinkles of water shooting out of my muffler..dont think it was coolant didnt smell like it..what do u think is wrong?

i started the car and engine still shakes like hell and still idles like a motorcycle... so i pulled out spark plug wire #1,2,4 (one at a time) and car stutters so i plug them back in but wen i pull out #3 car doesnt stutter so im guessin it has to do with #3 cylinder...i replaced the spark plug and still no better so im guessing its goin to be the injector? anyone?thanks..

Yes its ur injectors test it out

yea i had the same problem with my first ka it had 213k after a couple of hours i got some fuel injectors and that was it i also gave it a tune up because it was stallin somewhat

i did a tune up last year but didnt replace injectors so im guessing its jus goin to be the injectors..i already replaced my spark plugs/wires last year so im guessing its not goin to be that and should be good after new injectors..thanks to all who replied..

Sounds like bad/leaking injectors to me.

Change those motor mounts while your at it. If it shakes that bad they are shot (hockey puck it ftw)

[druthafoo]

This happened to me before. +another for probably being your injectors.

Gah and I'm the idiot who pinched an o ring when I replaced all the injectors thus causing the problem again.

[dennydizzo]

so i removed the injector with super difficulty but finally got a screwdriver in there and rotated my wrist til that sucker popped out!! it still looked good no bad o-ring or anything but tested it out and it was crapp...so i got a new injector replaced it and everything is dandy...plus engine mounts r still good..drives smooth and no shaking!!

yea i managed to have a riped lower o-ring on my #3 injector, thought i blew my head gasket, i lost power and was shooting assloads of smoke. i found some injectors on a altama at the junkyard, stole them and slapped them in and it ran way better and im at 230k on my motor
