The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

  1. check the air filter, good and clean?
  2. spark plugs in good working order?
  3. clean the idle air control inlet on the throttle body
to clean the idle air control port
  1. find a helper to push the throttle
  2. remove the inlet hose from the throttle body
  3. using a suitable spray cleaner spray into the throttle body and have your helper rev the engine to keep it from stalling. Don't spray to constantly just a quick one or two second squeeze
  4. let the engine idle again and see if its stable
There are a few other possible causes such as an old fuel filter or a fuel pump issue

Where is the trottle body

your throttle body is somewhere between your air box(air filter) and the inlet manifold. although some cars like nissan skyline gtr,s or the pulsar gtir have thiers on the manifold itself and has a throttle body for each cylinder. hope this helps.

Engine light on Toyota sienna 1999 system too lean code 171

On the inlet flex hose coming from the Air Filter to the Throttle Body, there is attached with 2 tiny screws the AIR FLOW METER,or by the side of the Throttle body,remove it carefully and remove the "O" Rings and use a carburator cleaner and clean the inside of it where the Hot-Wire is as the dust picked up by the filter will seat on the Hot wire and cause the false message sent to the ECU and makes car goes very slowly .

You do not state the age of the car or the type or the size of engine or whether it is petrol or diesel. On older E class models a fault in the over voltage protection relay would cause cars to be very jerky in idle. In general on petrol models I would start with the throttle body. Remove the air ducting between the air filter cleaner and the throttle. Make sure the interior of the throttle, the throttle plate and throttle area behind the throttle plate is really clean. Ensure that all all air ducting joints and vacuum lines to the inlet plenum are free of any leaks. On some engine variants the cam sensor oil seal over time can fail allowing oil to contaminate the electrical connection. Thoroughly cleaning the socket and replacing the 'o' ring usually fixes this. On diesels (3.2 CDi etc) the EGR feed pipe from the exhaust manifold around the back of the engine to the inlet manifold can become clogged with soot. Push a frayed bit of hand brake cable through it to clean it; clamping the cable in a drill chuck can make for a very effective flexible interior wire brush around pipe pipe corners etc. Any further information you can provide as per the opening statement would help in the diagnosis

92 gmc 350 pickup....rough idle..have replaced MAP sensor, fuel filter,PCV valve, and idle control on throttle body...still having the problem

This could be a couple of things:
  1. Check that you have not got any vacum leaks between inlet manifold and cylinder head.
  2. Check your spark plugs and HT leads are in good condition and not worn, reset gaps. If worn replace them.
Worse scenario is the head gasket make be leaking water into a cylinder. Get a cylinder leakage test done to verify any manifold air leaks or faulty sealing head gaskets.
Good luck, let me know how you get on.

Chevy S10 Pick 1995 - Sputters and almost stalls when accelerating.

You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.
