What's up with cold weather and EVos? I thought cars like cold air and it gives more HP. My car starts to idle funny and stalls sometimes during start-up now. Drivetrain starts o get more noisy. Interior starts to chatter.

 

You know, last year some people posted about the cold weather bad behavior. My car was fine then, but now it's really finnicky in the morning.

THis car ain't that refined, just give it some extra time to warm up and it feels fine. Cold air does make more power, but it does seem to make our cars run a little rough. I let it idle for about 30s to 1 minute, then drive very easy until it comes up to temp. I don't like to let it idle too long to avoid carbon buildup, fouled plugs, etc.

Thoughts?

Have you done any mods?

 

Yeah BR ST4 with 272/272 cams but wasn't like this during the spring and summer.

 

only thing I noticed is the walbro gets very noisy

 

I guess not many people have problems. cool

 

With this car warm up time in cold weather is critical. With mods this becomes even more so. Seeing as how you're BR STG4 everything is probably more pronounced than it would be with a stock EVO in cold weather. Just warm it up well and it should be better.

 

With my mods listed below, my car's a little rough until it warms up too. Probably the cams?!
