1988 Pontiac Bonneville after engine warms up to normal operating temp engine wants to stall out when you come to a stop whenit stalls it starts right back up Iam getting a fault code 43?
Code 43 indicates a fault in the ESC (electronic spark control) system. It usually means the knock sensor has failed, or the wiring to the knock sensor is faulty. When this fails it causes the computer to retard the spark timing to protect the engine, resulting in stalling, poor performance and reduced mileage.
the 1996 s-10 blazer 4.3 vortec has the computer in the engine compartment on the left hand side....if this is true, you cannot, I repeat, cannot adjust the timing.....the computer adjust the timing....you should be able to read it on the sticker under the hood..... ------- The timing is computer controlled - no way to adjust it, the computer does all of that for you.
Code 21 is coolant temperature high. A faulty thermostat stuck closed or a defective coolant temperature switch could be the cause. Code 43 is Electronic Spark Control. This can be due to timing being off. When setting the timing you need to disconnect the tan/black wire. If that doesn't fix it then the Engine Control Module or Prom could be at fault.
