Hi guys my mx3 is lacking power on bottom end also if im going 70mph on motorway then the car sounds like its doing 130mph, its basically screaming its heart out. also there is a metalic/air kind of noise coming from eahaust i think when accelerating, it sounds like a ballbearing rattling around in he exhaust or something, i cant find any holes in my exhaust and i suspected my clutch was on way out as the bite is very high and over revs slightyl when changing from 1st to 2nd, like its missing the gear or something. would anything cause the symptoms i speak of, thanks

Sounds like you need to do some maintenance to your car bro. Take it to a exhaust shop and find out where the sound or leak s coming from first and get that fixed. You may have a slipping clutch as well by the sounds of it but hat shouldn't slow you down when accelerating... It will just make ur shifts abit slower

You may want to do a tuneup on the car.. Change the plugs, possibly new wires, new air filter, new fuel filter (important) and disty cap/rotor. Once you do those things it should definitely help your car run abit better.. This is all the info I can give atm until you give us abit more detail or post a vid of the problems.

Ild find yourself a friend with a shop and become best buds, also check your flex pipe. That will make your car nice and loud as well as give you a bit of a rattle if its completely shot, but its hard to say since you said you checked it already so Im thinking you need someone with some time and a lift.

Otherwise as for your power issue, buy a big blue tank tap your intake and hold the botton down on your next straight :mrgreen:
