A Tech Question.....help!

[GOT2HAVESVX]

OK I got to work this AM and our maintence man was outside and said " I need to borrow your car so I can fix mine up!!!!!!! So I got to talking to him and somebody got him to move a bunch of cars from a lot so they didnt get crushed and theres a claret SVX there! He says it runs ok but it wont rev up past 5500 RPM's. He took the exhaust off thinking it was topped up but it still wont act like its supposed to. Not knowing enough about it to tell him anything I told him I'd ask someone. He says the body has been abused though. Gonna go look at it this week!
