Its only been happening since last week but ive noticed that my idle after the cars been warmed up for a while stays around 500 rpm and sometimes it goes down to zero lol but the car still runs fine. Its just a little bit strange, i dont know what could have caused it, I have a tune on it for over a yr now, i changed the battery over 3 months ago so any thoughts on this would help

PS. Everytime i turn the car off then back on its normal, then 10 min later its starts going to crap, when i get on it the needle struggles going through the range

Thanks, Phil

 

Try running the stock tune and see how that goes.

 

I would say it has something to do with your tune.

 

nah the tune has to be fine, ive had it on there for over a yr without any problems
