Hello,

I’m having some troubles with my evo 9.

When the weather is hot, the car doesn’t run well on idle. And it get worse when the A/C is on. It can actually stall when I do some pulls or push on gaz pedal quick. The AFR seems way off sometimes.

Got some mods: Air intake, turbo, exhaust, intercooler piping, gs2 cam.

I reisntalled evoscan after years. Not sure I logged everything correctly.

Anyone can guide me into this?

Thanks

 

Fuel trims suggest it's running rich. That would be consistent with the fact that it gets worse at higher temperatures.

I notice there's no MAF sensor data in the logs. If you can configure evoscan to read that data, and it reads too high (>2g/s at idle?), then that could be the source of your problem.

Otherwise check air filter, clean injectors, the usual.
