as i floor it in any gear it seems that after about 5k rpms there is a loss of power. before it would just push harder n harder, now it seems to push even less at high rpms.

what could this be??

on a possibly unrelated problem i noticed my exhaust got much louder lately. i tought i was the cold weather but i doubt it. it also makes a strange noise when you rev it up n then let go, it kinda farts or something??

could it be my cat is going bad or what??

 

you have an exhaust leak, or rather it sound like a separation. check the flange in front of the axle, between the b-pipe and muffler, and check around the cat/y-pipe, perhaps your flex section. as for the loss above 5k, i have no answers, perhaps the vias system, but i'm not keen on the symptoms exactly.

 

how many miles do you have on your car? If it's a lot you may want to clean your TB or check spark plugs for fouling. It could be a # of things.

 

the mailage is 78k, i dont think s dirty tb would couse such a power loss. the plugs were changes about 5 k ago.

from what i understand at about 5000 or 5500 the the second of the dual runners open up, so maybe its that second runner thats not openning??

 

It your MEVI, from time to time my car also does it. There are a number guys here on the org who knows how to mix it, but I'am not one of them!!!!!!!!
