Miata Fuel Issues
Posted: Sun Jul 20, 2008 10:43 pm
My dad picked up a 1992 Miata with 120k miles or so... I personally drove it around today! Drives great!
Issue is too much fuel on start up and at idle... We found this by trying to start it, crank crank crank. Pull the injector wires so it starves the fuel, crank crank sputter run die.. Plug in the injectors, crank run... No issues other than a rough idle with a rich exhaust smell. Drives great through the rpms.
We have a fuel pressure issue... Too rich on startup and idle...
Maf?
Fuel pressure reg?
Fuel pump?
Faulty sensor?
All this is running through my head...
