OK, so I am tackling the maf. Ordered one online but haven't got it yet. I did notice my coolant recovery tank is leaking. The plastic nipple fitting is cracked where the small hose goes in and looks like it was repaired at some point..unsuccessfully..This leak has basically sprayed the passenger side of the engine with coolant. Now for the dumb question. Can this be causing my misfire? Or screwing the sensors up? Am I at deeper issues than maf and cps? Coil packs got wet too, so?? I read a few posts with misfires in rainy conditions. Obviously the tank needs replacing but what other damage is possibly done?

thanks for any input
