No permanent idling control and back firing - Samurai Suzuki Cars & Trucks

faulty injectors or faulty injector control
loss of power is fuel problems ( pump or injectors )
loss of turbo boost is lack of extra fire from the combustion --back to injector or control and bad idling is injectors squirting/ not squirting and not atomizing properly

Year make and model helps...Clean the throttle body and MAF sensor. Clean or replace the idle air control motor.(IAC)

hi,
backfire means the ignition settings are wrong,which type of repair have you done before having THIS PROBLEM,
ALSO YOU CANCHECK THE AIR MASS SENSSOR.

Could be many things but I would scan the vehicle for codes which may hint to the problem. Some store like autozone will do a free scan if the light is on.

This type of problem can be caused by engine wear issues, shorted or cross firing spark plug wires, moisture in distributor, lean fuel mixtures and vacuum leaks. Check all these area's for problems

several things to check for this one....since its happening under a load.

- timing
- ignition (spark plugs, distributor, cap/rotor)
- Idle controller
- exhaust system

idle control sensor bad

Carb.basic setting.
On the Carb to Intake manifold there is an AIR/FUEL volume control screw. Gently screw it in Clockwise until it bottoms out, then back it out 2 turns.
Next, find the Throttle Butterfly Fast/ Slow idling screw, and back it out until the Throttle linkage is released.
Then slowly wind it back in 2 turns
If you have SPARK and FUEL up, then it should Fire Up.
When it does, using the Air/Fuel screw to stabilise the idle mixture, adjust the Idling Speed Screw to run balanced at around 750 RPM.
Happiness!!!
All the best and Regards, DT

ICM idle control module, loc throttle body, it may be dirty, remove clean or replace, its easy..

Take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most stores offer this service at no charge. The codes will help identify the problem. Sounds like a faulty Idle Air Control (IAC) valve to me, but the codes will narrow the reason down. Hope this helped and best wishes.
