need some help won't stop stalling
hi guys i have a 87 na 5 speed im having a problem with stalling everytime i come to a stop or have to put the brakes on hard. The engine will stall out ive checked for vaccum leaks and cannot find any ive also replaced the master cylinder after approx. 15 minutes of driving it will no longer stall at stops or hard braking
no idea what the problem is. it also idles irradically goes to 1200 then drops too 500 then jumps right back to 1200 does this non stop?
Any help will be greatly appreciated

id check the bac on the driver side of the engine. its adjustable with an allen wrench .its cylinder shape and connected to 2 hoses on it. try adjusting both ways and see if your idle will level out.
Check the BAC, make sure the TPS is set properly as in 1 volt and check the variable resistor for a proper fuel mixture setting.
jerzey in da house check your tps leave the bac alone also look for shorts. my n/a has a blck wire hanging on coils closest to the front of the car and check the CAS wires shake em around see if thats whats causing the stall (speaking from expirience)

In general, with these kinds of problems, the last thing a person wants to do is start messing with adjustments. The result will be an adjustment that is wildly away from were it would be, leading to other problems.

Adjust your TPS as per the FSM/Haynes.
Check the operation of the BAC valve.
Check the operation of the cold start cam and thermowax on the back of the throttle body.
DO NOT adjust anything until you are sure the problem is solved.
