po 300 code help

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.

lolwth just happened ?the site went from blue back to origanal red and format ,wow .i also should mention that the truck was very hard to start for the first time ,it took ten minutes to pick up the cylinders ,ran on 2 cyl for five minutes.then picked up the others.

hello is everyone mad cus i havent been on.lol

thanks for the help guys ,preciate it .wtf

i was beeing sarcastic ,has anyone here looked at this?i really could use alittle help .i replaced the injectors tonight didnt help any .fuel pres is 62.so wth do i do .com om guys some help here ha?

it can take a week before a reply lol goodluck

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.

I want to help...I really do. But I can't figure out what you're typing.
