Hey help here...it just started doing this? When I'm on the freeway, I'm like at 3K or alittle over RPMS. But wtf? my car starts shaking! Specially if I'm 4K or over! It shakes like crazy and damn, it just started doing that? I dunno when susp. was chaged last. But can anyone pinpoint anything? Who has had similar probs'?

 

maybe you should have your valves adjusted

 

Wheel balance, remove suspension and check bound/rebound properties. Is idle staying constant or is it erratic.

Oh I know what it is. You need a frikin' driveline and some U-joints. woo hoo. That's about 98% accurate. Also check your tranny mounts. Go with Mazda competitions mounts and tranny brace. I'll get you the part numbers if you're interested. Mazdatrix has the driveline you'll need if it's an FC and the U joints are rebuildable unlike the factory ones.

Yeah, that's what it issssss...... Please get back to me and tell me if my assumptions were totally wrong. Any clutch shop or shop with a lift can check this for you. It's quite easy.

Sound familiar T. This is what happened with the Blue one I'm trading you guys. Valves my ***. How about that 3 angle valve job or the adjustable cam gears. hehe.
