so I was going to see my granny and she lives on a 2 lane curvey country road, sounds like fun huh? well it was all fun until i pull into the driveway and get ready to shut the car off and noticed that it is vibrating very hard. I was running the dogshit out of it, so when i was leaving the it kinda acted like the battery was weak and had to try a little harder to start. so im drivring home and decide to see if it has lost any power and no it still feels like full power, but when it hits bout 5500 rpms the lights dim a little and then when i shift the get bright again . ok so now i am baffled and i am sitting at the house and just revving it slowly to see what it does. so i try to hold it at 2000rpms but it would go up a couple hundred and then fall back to 2grand. over and over again. and then i notice that my front/bottom engine mount looks like it is slanted and doesnt look like the other ones???? does anybody know what the hell is wrong with my car, it is 02 ex 5 sp, no engine light, the motor sounds like it is making some noise but i cant tell if it is just from the vibrations or what

not hard, just support the engine from below with a jack, put a 2x4 between the oilpan and the jack. Don't jack the up just support it. Then take off and replace one mount at a time.

will i have to change all of them?????and what would cause the misfiring, the plugs only have bout 8k miles on them. the car has bout 100k miles but the missing only started after it started vibrating like it is......maybe i have broke something in the bottomend idk???no smoke and it runs fine

do you have to change them all? You tell us.
Only if they are broke/cracked.
Hell, you might not have to change those at all.

How clean is the filter? it can make the engine act funny itf it is really really dirty.

Best thing is have a place scan the ODB II and see if it is throwing an error of any kind.
Of but a ODB II scanner you self an look up the codes here: http://www.troublecodes.net/honda/hondaobd2.shtml

Have a the tire rebalanced the wheel probibly through a weight. Or you have a bad tire or dented rim. Either way they will tell you.

ok but does that tell you how to diagnose problems????could the cv joint or the axel cause it has been clicking when i turn to the right...but that wasnt a big problem cause i have a friend with a totaled auto civic that i get parts off of. also will an auto civic motor mounts fit a 5 sp?

 
Rep Power: 812

cv joints have nothing to do with your problem.

Actually a bad axle will make your car ride funny. Also why would a bad engine mount throw a cel and dim his lights. What about your alt going bad? have you thought about that also. If you wanna see if the vibration is cause by a bad axle or wheel bearing. Dont be scarred put the front on jackstands start your car put it in first and let your wheels spin. If either your axle or wheel bearing is bad you will know due to the vigorous shaking you will see.

cool I will try that when this damn rain clears up....and what you were saying bout the bad mount throwing a cell???I assume you were talking bout a battery cell, and if so would that be the cause of the lights going dim after about 55oo rpms?I think the battery is pretty shitty, it is the one that came from the factory and it has been drained about 5 times(i have left my lights on several times)(and no i didnt hear the damn noise when you do it) so maybe the battery is just really weak
