Very weak engine
I just bought a 93 z28 manual trans. 70k miles. The car doesn't pull anywhere close to what it should. Struggles to rev past 3800-4000 rpm. It starts great and never dies, it's just weak. It is totally stock. Any ideas more than welcome.

Re: Very weak engine
What happens when it hits 3,800-4,000 RPM - misfires, total loss of power, or keeps running, but just won’t go past 4,000?
Has it been checked for a plugged catalytic converter?
At any point have you scanned it for codes, or checked the fuel pressure?
