I need help , My Evo ix was tuned a few months back the car iddled fine even with the AC on however, the clutch did rattle a little but I knew it was the twin disc that rattles a little due to the floating plates. Lately the car has been iddling really rough on a cold start ,usually after the car warms up a little it starts to iddle normal , today I wanted to drive the car when I started the car I had to try more than 3 times for it to fire up , after the car fire up I immediately noticed the car was shaking really bad and also heard a loud CLUNK sound coming from the front left end of the car where the transmision is . I shutted the car off checked the sparkplugs, AIR FLOW METER, injector plugs, vacum lines , everything seems to be in good working order but the car still iddles terrible and has a loud clunk sound . I started the car one more time and drove the car while I'm crusing car is smooth but the problem starts when I come to a complete stop the car starts to shake and the clunk sounds come back untill it eventually shuts off . I have a brand new odyssey battery , new spartech cop ignition new spark plugs gapped at 23 for e85 the car was fine it's started acting up 3 weeks ago and it kept getting worst untill today that it's gotten to the point Ii\ can't even have the car iddle without shutting off also, injector scaling is right on the money If anyone can help I will appreciate it .

HERE IS THE VID WHERE YOU CAN ALSO HEAR THE CLUNKING SOUND

How can I check if it's bad?

You can remove it and clean it and see if it gets better. You can try and hook up a scan tool and see if you can get actual values on it and compare to a good value.

Im going to hook the car up to evo scan right now to see if its throwing some codes

I hooked up the car to evoscan, these codes below were immediately shown

P0340 Crankshaft Position Sensor circuit.
P0335 Crankshaft Position Sensor circuit.

bad crankshaft position sensor? check the wiring on it, and check if its getting power ok. Basically checking the obvious. You might try unplugging it plugging it in to reset it. It sounds like in the end you have a bad ckp sensor though.

so let me get this straight the car drives fine?, when the clutch is pushed in the car does not want to die? Does the clunking noise happen only in idle and sound like somethings rattling around in there??

Exactly , the car drives fine when it's above 3000 rpm. Let's say the car is in second gear at 3300 rpms and i shift to 3 car still rides smooth even when i press and realease the clutch . In the other hand, when the car is at iddle it shuts down /shakes/has a clunking noise if feels like the a rollescoster ride that how hard and loud the clunking sounds is.

normally when you see the cam and crank codes together you jumped timing. Check belt tension and the timing marks
