I have a problem, I loose horspower at high RPM

[mr makarov]

From the start it accelerates fine, but then I step on gas the RPM goes up 4000 & 5000 with no "kick" to it, there is no misfires it just not picking up like it used to. Also SES light is on. I had this for 3 days know. Does anybody know what it is ?

I have the following Mod's:
ColdAir kit, ECU chip
Camaro 97 RS, 3.8l

could be a slipping trans, get the code scanned that is setting the light, and it will probly tell you the problem with the car.

Also I forget to mention I have bad catalytic converter, can it cause this?

[89IROC&RS]

BINGO!!!! a bad cat will act like a cork in the exhaust system, and will create more backpressure the higher the engine speed, and choke the engine, so you wont have any power.

[mr makarov]

Couple months ago then catalytic went bad, I talked to couple mechanics they gave me some crazy prices, one wanted $900 and another wanted $1200 to put a new one. But one of them told me that without a catalytic the car will run better, it just won't pass the inspection. So I guess he lied right?

[89IROC&RS]

no no, he didnt lie, he was talking about cutting the cat out completely, and just running strait pipe, a failing cat is a really bad obstruction.

as far as the prices, that does sound a bit high, the cats are expencive though, like 3-400 bucks, and hourly rates to install are usually the killer. but im sure you could find it cheaper.

[mr makarov]

Alright now I know what to do, thank you for your help.

[89IROC&RS]

well heres my 2 cents i say just rip off the cat urself get a nice piece of pipe and 2 clamps and clamp it on bingo gain like 2 ponies and no more shitty cat and when its time for emitions just put it back on with the clamps

[Joseph1082]

I agree!

[mr makarov]

The problem is that it comes in one piece, and since I don't have a welding machine it's not going to work out.

1200 bucks for...one cat? two? do you guys realize you can get cheapie hi flows for like $50 a piece? i mean unless the baffling is messed up what the hell is the difference?

[Chevyracincamaro]
