Yesteday my boyfriend bought a 92 VR4... He loves it, but a question we both have is why is there a beeping and a yellow light on the dash comes on sometimes and boost cuts? I tried googling it, but no luck. Car didn't come with a owners manual and Mitsu has discontiued it. Wondering if this is a bad thing, or just a cut off. Please let me know!

 

Figured out what the yellow light is, but why when making full boost there is a chime? Boost leak? Clogged cats? Don't know???!!
