CEL Code P0171

[redpr5]

threw that tonight

The PCM has determined that during testing, the fuel system for bank 1 was too lean. (Bank 1 identifies the location of cylinder #1, while bank 2 identifies the cylinders on the opposite bank)

thats what my printout says.
i had the hose on the top of the intake manifold pop off (which caused the CEL) but the light is still on. just wonderin if itll go off by itself or if i have to do something



and my throttle cable popped off my throttle body tonight too!!! YEA! go stuck gas pedals. (luckily that was a 5 second fix)

^right on.
i think im gonna swap my plugs soon. get a good set of NGKs or somethin (since ive read bosch plugs suck, and platinum/iridium doesnt make a difference and neither do the +4 plugs.)

All my lines appear to be ok. I searched for vacume leaks and found none. i was watching the o2 volts on my snapon modius and my long term fuel trim was at 25%. It would drop to 9% off idle. I also pulled the vacume line off the fuel pressure reg and sprayed T-Body cleaner into it. My o2 didn't register it. I think my o2 is bad. But I still need to check fuel pressure. Any more ideas?

Also, off idle the lean condition goes away! Any rpm above 1,300 stays in fuel control wery well. I think its an 02 sensor. I will replace it and post the results for anyothers with the same problem!
