Engine miss in hard rain

^^^ And they're cheap now too - at least the basic ones are.

Yes, A Scan Gauge reads codes and I think it's a good investment. As time goes on you'll need it.

I have an UltraGauge and it has paid for itself.

You need to find out what the code is for that Check Engine Light.

I have been thinking about getting a Scan Guage, does it read codes

I’m thinking that’s how the smart money would bet.

Old mechanics trick for next time. If it does it again spray down cap and plug ends with WD40. It displaces moisture, so if it stops missing you’re on your way to the fix.

The tuba fix is only applicable on certain models. It really depends on the configuration of the hood. Some RV's have a hood that positions the tuba directly behind a joint between the hood and the rest of the bodywork. That allows rainwater to enter through the small gap and go into the intake while driving in heavy rain. Some have solved the issue by adding weather stripping around the hood opening, particularly in the area where the tuba is, without having to cut/turn the tuba.

I will take a good look at the way mine is made, thinking rain water could go down between the windshield bottom and the hood, and straight into the tuba. when i wash again, will see how the water runs down. that could be the problem. might need to put a hood over it.

My 04 Pace Arrow never had the water problems but it loved plug wires. Being a hot rod builder I put Taylor high heat wires on it from Summit Racing and never had a miss after that.

this also was a problem with the Ford chassis, 99ish. they had a snorkel that was available to fix it.
