just got a 92' s13 coupe and it idles weird from like 1000- 700 rpm' but when the a/c is on it idles ok.. i just had the car for 2 days and all of a sudden it started idling really roughy and it dies out and the brake pedal is hard and cant be pushed in? so i have to use the ebrake to slow down luckily i was close to home.. i asked around and they said it could be the maf or fuses? lmk thanks

Give it a tune up. cap, rotor, new plugs,
then timing, look for vacum leaks.
clean maf with MAF cleaner.

brakes got hard because the car turned off, meaning the power to the brake booster or whatever turned off.

[xsparc]

maybe the large vac line to the brake booster came off/broke and now you have a huge vac leak. it would explain the bad idle and no more power brakes.

[shmiddy]

sounds like vac leak from somewhere
