When I'm driving lately, I noticed that the car is shaking. Before it shaked
so heavy that I cannot even drive (in fear of breaking the engine). I stopped, and let the auto care guys check, then they replaced the spark plug wires. (they said the car was misfiring, so it shaked)

Then my car does not shake so bad like it did before. But the problem is
the car is not smooth anymore, when I'm driving on the freeway, I feel
that the car is shaking slightly. (at around70 mph/ 3000 rpm)

can anyone tell me what kind of damage can misfiring cause? Or is it just
the clutch has been worn out? Please, I really need help.

Thanks

I get a very sligth shake in my car (45K miles) I assumed it was the engine mounts. Would a misfire throw an ECU Code?

the only shaking a clutch would provide would be right at shifts.... once the clutch has matched speed with the flywheel, it wouldnt shake anymore...

so no, it doesnt sound like your clutch.


BTW, when your clutch starts to slip, thats when you need a new one

Have you had your tires rotated and balanced?
what he said, also see if you need an wheel alignment

I have already done the alignment, and rotated the tires too. The problem
is the car seems strange to me now, the ride is not smooth anymore. Would it be the suspension system? But it doesn't make sense, how can misfiring damaged the suspension system? Any other ideas?


Thanks
