How it happened: I was being stupid and raced to another street light against another car. In 3rd gear my RPM's decided to bottom out at 4,500RPM's. This was the first time that ever happened (it always could go to about 7,000 RPM's if I really needed the horsepower to speed up). Ever since that day my car's performance has been lacking. The pick up and go is not as great as it was. The RPM's still bottom out at 4500RPM's on 2nd, 3rd, and 4th gear (I haven't tried 5th).
I definitely want to get this fixed but before I go for a diagnosis can anyone tell me what to expect? What is it? About how much? Thank youMy Car Won't Go Over 4500RPM's and Lost Some %26quot;Pick Up %26amp; Go.%26quot; What's the Problem?Could be the catalytic converter restricting the exhaust flow. This would inhibit higher revs and definitely diminish power, while there would be no other apparent symptoms, possibly.My Car Won't Go Over 4500RPM's and Lost Some %26quot;Pick Up %26amp; Go.%26quot; What's the Problem?$750 for a new system including a hi-flo Cat is a fair price. Hey, if interested check out my Firebird at http://www.cardomain.com/ride/ Gonna do my exhaust soon, too.
