hey hows it going i was wondering if you guys have ever had probems with ur fuel injection.. when im driving my truck almost every time it runs fine and then it starts to fuck up.. i cant give it more than like 1/4 throttle before it starts boggin out. it seems like its starts flooding out because some black smoke comes out the tail pipe.. after i drive it for a while it goes back to normal. anyways let me know if u guys know anything about this... oh and now when i first start my truck up and its cold it starts to bogg from 1500-3000 rpm and then it goes away when its warm..
if u guys could help me that would be great
thanks alot

check your fuel filter and in tank screen I had a similar problem and that fixed it right up

When is last time u replaced o2 sensor.Also,get some throttle body cleaner and take the rubber hose off the throttle body and clean it good as well as the MAss Air Flow sensor.After proloned use those things get really dirty and can cause the problems u descibe.BJ

well i fixed the problem, i guess it boilded down to the fuel pump not putting up enouff fuel pressure so i put a toyota truck fuel pump in and now she runs fantastic... alot better response,,, should be ready for a turbo soon...
