Please don't text message here. Sentences, punctuation, and proper spelling will get you more and faster responses. Start by changing the harmonic balancer. The bad balancer may be causing a knock that is picked up by your knock sensor and interpreted as pre-ignition. If so, the PCM will retard the spark trying to get rid of the knock, causing poor acceleration and lousy fuel economy. In addition, the bad balancer may soon destroy the crank position sensor that sits right behind it, and/or tear up the vanes on the back of the pulley. Then you won't be going 0-5, let alone 0-60.

Also, when was the last time you did any tune-up items (plugs, wires, PCV, O2, etc)

What octane fuel did you put in the car?
What brand of plugs?
What brand of wires?

I REALLY hate reading run on sentences with very little to no punctuation.

ok well i changed the harmonic balance,r no more noise runs great, but no more power it is a very slow car i guess, can anyone tell me there0 to 60 times on these cars all i have is a k&n air system and 10 almost 11 seconds is pretty bad if it is 205 hp 260
ft pounds torque, seems like they would have more pickup.

Get a scantool. Check for KR (knock retard). I can guarantee that you have cracks in your exhaust manifolds. You may not see them, but they are there.

Also asked many times, What octane gas are you putting in? It MUST be 91 or better. Honestly, there are so many factors that can cause this type of problem, and a scantool is a great tool to start off with.

Also if you are wondering, your 0-60 SHOULD be around 7.6-8.0 stockwise.

Where are you located? Maybe someone is in your area that can lend you a scantool.
