Motor Sputtering, please help!!
 

i have a 90 miata that unfortunately is not turbod yet. i am puting all the pieces together still and hope to have it up soon. however, until i get to that i still drive it every day. unfortunately, it has a sputter through any gear. if you don't give it enough gas on take off, it sputters the whole time until you take your foot off the gas and press it again. or if you are in too high of a gear and press the gas. mostly when you push the gas too hard. it wont drift now when i want it to because instead it just sputters. any ideas?? please help. thanks.

do a search for shortnosed crank, and bad afm if supramans advice bears no friut. Also confirm that you have fuel pressure.
