I have a pro tune from the previous owner and all has been well until recently.

When I have the A/C on and take the car out of gear the RPMs drop to around 200-400 RPMs. This doesn't always happen and some days it works just fine.

On random occasions this happens even with the A/C off. I also have had the car stall a few times when taking it out of gear.

I initially thought maybe a vacuum hose came lose but then I feel it should be more consistent??

I'm posting my log in hopes that something stands out.

I have an Innovate XD-16 w/ LC-1 but I am not sure if it is tied to the ECU. It doesn't seem to be reporting here. Any ideas how to check this?

 

Try getting a tune on Speed Density...

 

better tune. Doesn't look like with the mods you have that you should be having this issue.

 

I will look into this, thanks. I've seen it befe but don't know much about it yet.
