i have an 03 sierra 1500 and for some reason when its raining or when there is a ton of rain on the roads my truck starts to reduce power in the engine and the engine light comes on. usually above 80 km. when its dry outside tho, it doesn't happen at all.
annoying as all hell. can someone help? thanks.
