Hi i went to start my car up today and when it started, it just started to rev high and the wheels spun. i try to accelerate but it just stalls. when its warmed up it can accelerate but when i take off the gas the wheels keep spinning for about 3 seconds and then stop. it was working fine last time i took it out.

I have changed fuel to 15% nitro would this affect the car.

it also idles very strange. it goes up and down.

it freaks me out PLEASE HELP ME!

Did u retune when you changed to 15%. If not try that. I'm not too sure but it sounds like you have an air leak somewhere. Trying changing the fuel lines and sealing the rest of the engine. Im not sure how to seal the engine, better ask someone else.

sounds like you need to re-tune, What car do you have, try to get the factory carb settings then tune from there.
