Rev's drop when vehicle comes to a stop and sometimes cuts out


There are many factors that can cause this condition. Since I have no direct familiarity with the "Citi Rox" engine (I do not believe we actually have that engine available in the U.S.), I will assume it is a GASOLINE (PETROL) engine, not a diesel engine.
If the vehicle has high mileage (over 100,000 miles), check the following:
  1. Is the CHECK ENGINE light on or flashing? If so, take the vehicle to a local auto parts store and have them scan for codes. Look up the codes they find on the Internet, and that will help in your diagnosis.
  2. Of course, replace the air filter if it is dirty, and make sure there are no obstructions in the air intake.
  3. Inspect the throttle body. If it is dirty, clean it with an approved throttle body cleaner for your vehicle, or have it cleaned.
  4. Inspect and clean the IAC (Idle Air Controller). Also inspect the EGR valve (Evaporative Gas Recirculation valve) to be sure it isn't leaking or otherwise compromised. The IAC is often the culprit in this condition but sometimes a leak in the EGR valve or its mounting gasket will throw the computer off far enough to where the car will not run correctly.
  5. Did the vehicle sit for more than three months recently? If so, either replace all fuel in the tank or, at least, treat the extant fuel with Fuel System Water Remover, then fill the tank with new fuel after driving about 100 miles (150-ish km) with the water remover in the tank. Once you have filled the tank with new fuel, add Fuel System and Injection Cleaner to the tank and drive for another 100 miles (150-ish km). If your performance improves, you'll know you had old or compromised fuel in the tank.
I hope this gives you a starting point!

89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed


This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--

Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.

Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.

You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.

These can be if the vehicle has them cleaned using a special zero residue spray cleaner.

First have it scanned to see what if any errors it shows--the computer.

My vehicle stopped dead at set of lights and would not start, called RACQ he installed new battery $165 Stated that was problem, drove less than 1/2 kilometre down road, felt the vehicle ****. Continued...


Sounds like you have a fuel issue. It could be a fuel pump cutting in and out. It could be fuel pressure regulator, or an injector not spraying correct. I think it's time to find an honest educated repairman.

Cranks right up but cuts off immediately unless the gas pedal is pressed


IF YOU RECENTLY UNHOOKED BATTERY OR HAD DEAD BATTERY THE COMPUTER WILL NEED TO RELEARN IDLE STRATEGY,START VEHICLE KEEP IT RUNNING AND DRIVES ON 2OR 3 MILE RUN SHOULD BE SUFFICIENT IF THIS DOESN,T WORK LOOK FOR VACUUM LEAKS IN ENGINE COMPARTMENT OR POSSIBLE BAD IDLE AIR CONTROL LOCATED NEAR THROTTLE BODY

Shackes and cuts out


What do you mean by it "shakes & cuts out while driving"? The vehicle literally shakes, or just the engine shakes at an idle or while driving? and it cuts out when, at idle, driving? Let me know when specifically it has this problem, it might help me on giving you a better suggestion(s) on what problem(s) might be causing this.

Corsica stalls at stop signs


sounds like the EGR valve is sticky, take a small screw driver and tap the valve when the engine is at idle and you will notice a change in the way the engine runs, if the vehicle smooths out disconnect the valve and drive the vehicle and it should not cut off please let me know and dont forget to rate me!!

Car idles good revs up good but when i put it in drive or reverse it stalls


dear friend-the reason why your vehicle cuts is because as soon as you engage the idling drops,fitted to your vehicle is a module that picks up the idling,find that unit and your problem will be solved.
