Need help quick

[davo]

Guys

My battery went up the s*** yesterday and the car has had no power for about 18 hours now. I have just placed a new battery in her and she is idling all over the place anywhere from 0- 1500rpm is there a quick fix or is it a mazda job???

Help required asap.

Regards
Dave

Sounds like either the new battery is crap also and/or you're having alternator problems.

hmm i'd be
turning all the stereo gear off
disconnecting the negative terminal, and jamming foot on the brake for 30seconds
leave terminal off, and reconnect...

also put the windows down, and leave car out of gear so you can start her without openeing the door... leave it to idle for 10-15minutes, then switch it off...

soudns as though the ECU is having a bit of trouble re-training
