Hello Scotty,

Love your show big fan.
My question is I have a 1992 Mazda Miata 1.6L that will start but dies once it hits 900rpm. I already changed the fuel pump made sure that there is no leaks. any ideas why its doing that.

pressure test the cat, it may be clogged up. if not, a clogged fuel filter or bad fuel pressure regulator will do that


Thank you! ill give that a try
