Ever since I got my unichip and lightweight pullies...whenever it rains-- its seems like my car will drop out of gear into nuet... rev a bit. pick a gear, goto another gear... the throttle is choppy...etc etc, but when it isn't raining its fine...

finally the SES light came on and stayed on after the rain and im not sure what is wrong with my car... dealer says it maybe a MAF?

 

strange..........keep us posted on what the dealer says
