Hey Guys,
Lookin for any help i can get on this.

When you turn the car on it turns a rev limiter on and u flip the key back and turn back on and it clears it and drives fine.

Now I originally thought thay it may be a Vacuum Line, but if it were that it would been there after the car was turned on. Now I am thinking that it has something to do with a sensor.

It does have a b16 swap on it if that makes a difference.
Help Please!!!

Thanks a lot.
