#32 of 35 Engine cycling without computer error by greg109 Jul 12, 2009 (4:40 pm)
Yesterday I was driving and my beloved 01' miata started accelerating on its own. I pushed in the clutch and slowly eased on the brakes and the rpm's stayed at a constant 4000. I pulled over thinking that my throttle cable had gotten stuck some how, but to my surprise it wasn't. The 'check engine' light didn't come on, so I didn't know what it could be. I disconnected the battery cable to reset the computer and started it back up and the engine starting cycling like someone was constantly revving up the engine. I drove it back home all the while it would rev when the clutch was disengaged. I replaced the throttle positioning sensor...$157.00 and it's still cycling. Does anyone know what could be the problem. I'm a great garage mechanic, but this has got me stumped.
#33 of 35 2001 Instrument/Gauge Failure by chris1969 Oct 08, 2009 (5:37 pm)
I have experienced an outage on my gauges. I have changed the fuse repeatedly. Once replaced, the gauges will work for a minute, then blow the fuse. All other electrical seems to be okay. I have resorted to purchasing a bunch of fuses so I can check the fuel level periodically. Help, please! Replies to this message: ateixeira (Oct 09, 2009 7:16 am)

Replying to: chris1969 (Oct 08, 2009 5:37 pm) Must be a bad ground. I've never done much electrical work, only installed a couple of stereos, but I bet that's what is causing it.
#35 of 35 Headlight control by xyla Oct 27, 2009 (11:44 am)
2007 Miata GT - is there a louder alarm to keep from leaving headlights on? Is there a add on control unit to turn headlights off when ignition switch is turned off? Thanks for any help
