i converted my car to mpfi started out with like 3 cel codes fixed em all, but it wont redline like it hits around 5500rpms then like misfires or something makes like a weird rev limiter noise then like bogs down a little then more then more until i shift i have no power cuz im shifting at 55 right before this weird redline other then that it runs great, and sometimes i get a code 43 on my ecu but my check engine light doesnt come on

 

can sure your distributor wires are backwards, meaning the two white wires.

 

already did that when they are the other way it wont start
i dont know what to do about this like i drive it all day everyday and the cel only comes on when im on the freeway and even around town it wont rev all the way its not in limp mode cuz it hits 6 then revs down all retarded if i keep it floored and like it bogs and makes a missfire sound if anyone knows

 

i had a motor that did this same thing but sold it before i tried fixing it. good luck.

 

okay well if i dont find out something to do to fix it im going to a local performance shop where a couple friends own and operate to have it looked at but id rather have all the work done myself thanks in advance
