I have had problems with the vehicle stalling in the car wash and with heavy rains. I had maintenance done on my vehicle in May of 2016. While replacing the spark plugs and wires, they found I needed to replace a rusted coil. The vehicle ran good except the occasional stalling in the rain. Now for the last 3 months, I have been dealing with intermittent battery drainage with no idea why. Sometimes it will drain in 8 hours and other times I can go 2 weeks without it draining.
I just finished washing my car Saturday and for the first time my engine which is a brand new crate engine has hesitated for the past few days, runs bad, and won't accelerate at all. I am pissed and don't know what to do. Any suggestions.
