My Rx7 has had nothing but electrical problems so far...the beeping just started out of nowhere and my brake light came on shortly after so i change the brakes but the beeping continues no dummy light or anything anymore but the beeping comes and goes it beeps 4 times stops then beeps again also at least once a day i have to push start the car to get it started and usually its in the middle of the day, never in the mourning. any ideas?

 

not really sure what the problem is, but you could look at the factory service manual found here:

for the 1986-1988

and here for the 1989-1991
http://www.teamfc3s.org/main/factory...ual/1989_1991/

 

could be a leaky injector, maybe some minor flooding after you run the car for a while?

 

the FAQ at the top has common beeping "codes" and what they mean
