no codes...may have to guess ?? replaced entire rebuild 6 months ago..would hope intake gasket..ok...just started...and it goes away for maybe 1000 miles then comes back random...hwy drive..seems to help. hmmmm
man don't forget to bleed the anti lock break system ..fixed mine right up...on the antilock box where all the lines go on the fender...small black rubber cap has a bleeder under it
