Re: '89 Cavalier 2.8L Z24 won't accelerate over 25mph, car just jerks.

the compression could all be 50 psi it would still rev up and accelerate you don`t have a compression problem. I would get a scantool & look at injector pulse with sounds like your not getting fuel delivery to the engine. should be TBI if so you can look in the TB and rev it up under the hood and see your fuel spray just dumping everywhere at WOT. IF you can`t then you have got injector or PCM problem. signed, always stuck in diagnostics!
