check the vacuum hose on the brake master cylinder on the firewall, THAT part sounds like a vacuum leak, i had the same problen when i disconnected that little vacuum tree to adjust my clutch cable a few months ago, brakes got stiff like they had no power assist, and it would start idling weird and eventually die. as for the other the misfire thing would be the best place to start i think.

 

could an ignition module cause these problems im going thru and how can i check that

 

alright so i think i found out what the problem was last night i was checking voltage with meter on all sensors just with key on and motor was not running. Then i had leaned on the alt and noticed it was hot that was weird i had not even turned on car all i did was pick up batt and connect it again and turn on key. So now i have to take my alt to autozone to get it checked that it can be some kind of diode or something like that.
