bad MAF and MAP
2002 ws6-m6 open headers
Ok i am throwing P0300, which could be caused by P0101,P0102,and P0106. Have had this random misfire for 5 days ( went through 2 in. puddle of water and it all started) I already replaced plugs, wires, and o2 sensors. Just replaced the MAF and it is still misfiring horribly. Hoping that the MAP could cause such a severe misfire of all cylinders

Ok replaced the MAP sensor, still misfiring, and its an act of god to rev above 3,000. My only other options are crank position sensor wires are grounding out or got wet. Is it possible for the the timing gears to be off ( after a puddle of water)? Valve seals are fine not burning oil, hope I didnt bend multiple valves.

Ended up being bent # 8 intake/exhaust valves, # 6 Intake valve with broken spring. My header gasket had water between it and head, so theory is water traveled through either the headers, or got by the gasket into #6 and 8. Thanks everyone. Hope
#6
Doing what? Water in the cylinder will not break valve springs.

I was running open headers that day, trying to get off the road before rain got worse, hit a puddle, and the madness started. Pulled the cover and saw the spring on the 0 psi cylinder. top coil of spring just separated by an inch. The valve was bent also, more severe than the other 2 valves.
