You need to get the faults codes from a visit to Pep Boys or Autozone etc and they will read your onboard computer codes and tell you what they mean.
This diagnosis will help with the fixes
Sounds to me like an accelerator/fuel sensor

SOURCE: check engine light came on...

Bring car to an autoparts store that features free diagnostic tests. They will pull the codes that triggered your service light. Post back here with the codes for diagnosis.

SOURCE: Car starts poorly during cold mornings. The idle

Sounds like a cold start valve (which is actually an additional injector in the intake to assist in cold starting) If you can get it to your local prts store while the light is on they will read the codes for free and tell you what the car thinks is amiss.

SOURCE: engine runs rough whsn idling

check the timing, it might be out one notch. also, check the torque converter and maybe the censors while you are at it just to be sure. otherwise, check the main brain of the car.

Here are the most common causes of idle surge, rough idle esp when cold, other symptoms include stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Please tell me what is causing my toyota wish to shut off when i slow down and try to stop


This all depends if it runs good and not rough or skipping then i would say to check the idle control valve. this valve is what controls the idle and if it goes bad then it will cause engine to idle high or low and make it stall at stops. this is what i would start looking at first, you can try to remove and clean this valve and see if that helps but if not then replacing it may be needed. good luck.

You may want to check the Vacuum lines if there are leaks. Check also Fast Idle Thermo Valve, which controls the idling at cold starts. If you have a carb, check the idle up valve.
