ill have to get the actual error code tommorow, but one had to do withthe maf(mass airflow sensor) which i cleaned and it went away, but there were 2 that said the engine was to lean? it was pli p0107 or somthing(ill get them both tommorow) what is this saying, is a sensor off or busted?

Get the codes and we'll work from there. You don't happen to have an exhaust leak before the O2 sensors do you?

p0171 system to lean
p0174 system to lean
p0101 MAF or FAF a CKT Range/perf
^that one i just had to clean the maf sensor and it went away, but are the others steming from this one?

There is something feeding wrong information to the PCM leaning out the mixture. It is possible that the MAF is reading incorrectly, causing the othe two codes.
P0171 - Fuel Trim System Lean Bank 1
P0174 - Fuel Trim System Lean Bank 2
How long has it been since you cleaned the MAF sensor?
Here are some checks that are detailed in the Diagnostic Chart for this code combination:
Visually and Physically check the following items:
[ul][*]The exhaust system for leaks[*]The fuel filter for restriction[*]The air induction system after the MAF sensor for vacuum leaks[*]The vacuum hoses for splits, kinks, and proper connections[*]The throttle body, intake manifold, and EGR valve for vacuum leaks[*]Idle air control (IAC); if a high or unsteady idle is being experienced[*]The positive crankcase ventilation valve (PCV), spring, and O-ring for proper installation[*]The AIR system for proper operation (if applicable). An AIR system that allows oxygen to enter the exhaust may present a lean condition.[*]The fuel for excessive water, alcohol, or other contaminates[*]VCM and sensor grounds are clean, tight and in the proper location[/ul]
And if you could do me a favor and put your vehicle information somewhere in your profile so that I don't have to dig around for it. LOL Thanks!
