I just removed my air pump and acv and made a block off plate. I changed the oil with 20w-50 synthetic, and filled witha full thank of premium, it idles fine, but sometimes when I'm driving, the car will just die. anybody got any ideas?

 

Im not sure where it was i heard it, but im pretty sure your not supposed to run synthetic in a rotary.

 

Something related to the ACV blockoff plate, I'd guess...Are you sure you blocked off the exhaust port well (where the round check valve thingy goes)?

 

also dont put premium. put 87 in that bia bia.

 

whoa... did they really make 20W50 in synthetic? I mite have to look at that.
But anyway... dying... have you used premium before? As SirCygnus stated... u don't need premium unless you're turbo and making higher than stock boost. Stick with the 87
