I have 1992 RS Camaro 25th anniversary I replace spark plug /wires, distributor cap and rotor, oil filters, air filter, vaccum hose,fuel sensor, idle speed sensor, but when Idle the car run good but when I stop at traffic light orturn my AC engine cut off. What could be????

TPS sensor and IAC sensor.

Have u checked the cadeletic converter. It can do funny things

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

sparkplug wires?

CHECK FUEL pressure and take a fuel sample see if has water in it. since started problem rt after getting gas sounds lik you got some bad fuel

I would change the spark plugs, spark plug wires, distributor cap and rotor, fuel filter, check and change air filter if dirty, check timing, check and top off all fluids, check or change transmission fluid, check brake pads/.shoes and drums/rotors for wear and check tire pressure, check the condition of all belts and hoses and replace as needed, check condition of radiator antifreeze and top off or replace as needed.

The precatayltic O2 sensors or sensor may by malfunctioning.These are the O2 sensors that tells the ecm to adjust the air fuel ratio according to how much oxygen content is in the exhaust.If for some reason it thinks to much oxygen content is in the exhaust it will tell the ecm to add more fuel.The post catalytic O2 basically is used to monitor the catalytic converter function and should not adjust any air or fuel. Is the check engine light on and are any codes presnt?

Replace the pick up coil in the distributor,this is the problem.

well, need to check fuel pressure, spark. Ignition module in distributors go out that is common

Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
