lean codes...sigh
alrighty guys, i know i know did you search first.... YES, but i have so other things as well.
i got the P0171 and 0174 codes...lean in both banks. im also having idle issues. when i stat it, its good until the idle drops to around 750(normal) but then dives well under 500 and nearly dies... ocasianaly it will, even at a stop light. im also having cold start issues, when i havnt drove the truck in about a half hour i have to crank on it for a while, or prime the pump 2-3 times(clicking the key on and off before starting). altho i think it may be somthing else like a check valve in the pump. this proble has been ongoing for quite longer than the codes. im also getting **** poor mileage, but its a sohc on 33's and stock gears...
thoughts, direction, and help are well welcomed!

can anyone tell me where this elbow would be on a 95 4.0. I've looked at a few of the tutorials but they all seem to have the pcv near the throttle body but I'm not seeing on my truck but i'm having the same symptoms. Rough idle lean codes in both banks P0171 and P0174. I cleaned my maf and that didn't seem to do anything for me. Any help is appreciated

hmm then thats probably not my problem. Doh I was hoping it would be something simple. with 218k I really don't want to start throwing parts at it

that little sucker just pisses air out. All the other hoses and lines seem good although there could be other problem area's once the area is actually able to pass that section. Any experience with fixing this seal?

opps I guess my arrow didn't come out so well the line that I am referring to is the metal hard pipe that is right behind the AC pipe. The metal pipe is question goes from the Intake manifold to the left header. I believe its for the EGR system? I'm thinking about just mixing up some jbweld and sealing that sucker up.
