Re: losing power

Clogged catalytic converter, major tune-up, bad tps...lots of things could cause this. Getting a check engine light?

Re: losing power

Still running muffler? Not enough back pressure maybe? When's the last time a major tune-up was performed?

Re: losing power

Copy on the cat...actual muffler still exists, yes? Pull the plugs & see how they look.
