[Ramsey]

hey guys long time since ive been on but as most know i demodded for awile now till i have time to do front mount .
heres the deal ,ive had to do a crap tonof work to get this thing back to semi stock but i finally have it done and its skipping and throwing a po 300 code [multiple mis or random i forget ].i changed the plugs thinking my tr6s were wrong for it anyway but no help.wires seem to be ok.i guess first wat would cause a po300 ?ive had to ,install a new intank fuel pump ,rewire stock injectors ,rewire maf ,o and a good old transmission again,[thats y i took it off the rd.sick of them lol]i also had to rerun all vacuum lines to factory locations like pvc etc.it been alot .so could any of this stuff be causing my issue?idk like i said maybe just start with po300 and let me know wat that could be .thanks guy ,new site color looks nice .

o ye by the way ,should anything happen when u unplug the maf with it idling ,?cus i did and nothing changed ,not worse or better.i did that because i had to rewire the maf and i had a questionable connection.

I had that code and it was a failed rocker. Check all the rockers and look for a bent pushrod. Mine was absolutely quiet on the valvetrain since the lifter stuck up in the lifter retainer.

interesting u say that redc .hmm.wen i powerbrake it to see if its still sputtering i get alitle poping like a rockers off,not bad but alittle pop wen i give it gas and hold the brake.ill have to try looking at them.but the kicker is wen i parked the truck a year ago almost i dont recall it acting that way ,but i did spike boost real high wen the input shaft broke and i never ran it again,so maybe it happened at the same time and because i never drove it after breaking the input shaft i never knew .thanks ,off the wall but possible.im still open for suggestions guy cus i am broke down until i figure this out.
