My car has random misfire but dont throw SES light what could it be? and gets real bad if it rains hard. i run TR6s for nitrous i have Stainless Works LTs and msd plugwires and some are very close to touching headers..

i heard if they touch it could calls it to misfire is that true?

but im lost why it gets worse when it rains

so i dont drive it much at all

 

could have burned though a wire of one of ur o2's get wet which causes the misfire its common

 

anyway to fix the o2?

 

there is no way to fix the 02. But if the wire was broke or burnt, your check engine light would be on for sure. unless your check engine light bulb is burnt out... to check turn the key on without starting the car, and see if its there. simple. to me it sounds you need new spark plugs and wires... depending on when the last time you did plus, maybe just wires. Do a thourough visually inspection, even take them off and look at them. also, clean your MAF for the hell of it. with "MAF cleaner" at napa. that stuff is good to have in stock anyway.
