My rich engine code is back.
At idle I sit on 15 on my vac gauge. and hear a huffing noise on cold starts. the loud sucking noise happens threw the air filter and only when cold.
when I turn on my AC with my foot on the brake s sinks a bit and the huffing noise gets louder.
after the car is warm no issues with huffing noise.
Anyone experienced vacuum conditions like so.
yes I have tightened every intake clamp etc.
should the brake pedal sink a small amount when the AC is turned on.
