My '93 (1.6l) will sputter and act like it's not getting gas when the engine is cold. Only happens when accelerating from a full stop, but sometimes it will carry a little hesitation into 2nd gear.
Every once in awhile it will have a mild backfire. New plugs and wires did not solve it. Any ideas?
Motor is shot. ;-)
^Tired, yes. Shot, no.
Any codes -> http://www.miata.net/garage/isc.html
Don't think so but I'll check tomorrow.

Did you sell the car or what?
Would a flaky AFM produce these symptoms?
Mine does this somewhat when cold, too. Let me know what you find.
Looking more and more like the AFM. Car died this afternoon after I got home from work and wouldn't start. Disconnected the AFM and it would start, but die as soon as I gave it some gas.
Replaced the AFM. The car is running well again, but still sputtering when it's cold.
Thermo sensor on back of block? Got a spare stock ecu if you want to check that.
Thanks Steve, I may take you up on the ecu. I did check codes again and had a '1' in there.
Perhaps a dumb question, but have you checked for vacuum leaks?
^Not dumb and I have. I am starting to suspect the corrugated section of the intake cross-over tube.
When was the throttle body and butterfly cleaned?
^Last week....wasn't that dirty, but I cleaned it anyway.
It might not what you have. I just know the wire to the plug of the MAF is very sensitive. My NB didn't even start after I messed around. I than wiggled the wires and pushed them into the plug and wraped it w electrical tape. Problem fixed!
The 1.6 doesn't have a MAF, it has an AFM (air-flow meter).
