car wont rev pass 4k
If you jump the service connector and the check engine light stays on (constant) than it doesn't have an error to report. I would reset the ecu (pull the 7.5A Backup fuse from the under-hood fuse box for 20s) and drive it again. If it does it again, shut it off, jump the connector, and turn the ignition on and see if it flashes.
Sounds to me like a timing problem.
Some info about your car would be helpful - year, engine, model, etc
