what do these codes mean

DTC #1 P0352 Ignition Coil B Primary/Secondary Circuit

DTC # 2 P0303 Cylinder 3 misfire Detected

DTC # 3 P0304 Cylinder 4 Misfire Detected

DTC # 4 P0171 System Too Lean Bank 1

DTC # 5 P0174 System Too lean Bank 2

Sounds like a bad coil pack.

yeah, for this misfires, but the lean codes are probably intake manifold o-rings/gaskets (i'm assuming it's a SOHC V6).

Thanks

yeah its a V6 not sure about SOHC but could it also have something to do with the air flow intake censor

i doubt the MAF sensor would cause a lean condition = too much air/not enough fuel. this is usually caused by vacuum leaks. this is fairly common to both the SOHC and OHV V6 engines (espically the SOHC needing upper/lower intake manifold gaskets), but a vacuum leak anywhere will cause this problem (hoses, PCV elbow, PCV grommet, any vacuum line leaks, a cracked intake tube after the MAF).

Ok kool, thanks for your help.
