      What's the CEL?

      If there's a CEL, something is WRONG. Nine times out a ten, fixing the CEL will fix whatever issue you're having.

            Is it stock motor? My friend swapped an F22b Sohc Vtec motor and that would happen because he didn't have the right ecu or Vtec wired

                A CEL will usually cause the engine to run in "limp mode"... and you should never rev an engine throwing a CEL high anyway. That's just asking for a blown engine! It's like feeling a pain in your ankle, and then deciding to run as fast as you can.

                Whatever is throwing the CEL is likely the culprit, or the CEL itself throwing the ECU into limp mode. However, the valve timing may be off (belt skipped a tooth), or the ignition timing may be way off.

                  You should find out if you're friend has had any type of swap, or major work done. Sounds like It's running in open loop. So if the motor and everything under hood is basically stock, then start with checking the o2 sensor. especially if the code happens to be a 41. If he has had a swap or anything done... then start looking into bad wiring/splices etc. It's really common to have an old poorly twisted and taped splice, fall apart.

                    yes the cb is stock original engine and tranny..
                    8 -TDC - top dead center sensor

                    15- Ignition output signal

                    these are the two codes it gave me .. when i read the blinking lights so i asked him if he had change the distributor, and he said yes cuz his car was stolen and the just took a few thing off the car including the distributor so he got one from the junk yard so i told him was the car running fine before and he said yes in till he put a use distributor on it. so we all this info i came down the conclusion that he has to go exchange the used distributor or get a refund and buy a new one..

                    Also The D4 light was blinking when i jump the plug to check the codes so does the part that is wrong with the engine wich is the distributor effect the tranny also.. is my question

                      Once you fix the distributor everything should go back to normal

                        That's What i Am Hoping ,, let's see once we go tomorrow and exchange the old distributor for one that is actually good and to save us the hassle i told him we are gonna swap it out right there in site just in case we get the bad luck of another faulty dizzy ..

                              You're not "redlining". It's a fuel cut. A safety measure programmed into the ECU to prevent (or try to prevent) engine damage. Fix the problem the CEL is alerting you of, and the 4500rpm fuel cut will stop.
