AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question Okay, I have a Toyota Camry 95' 4 cylinder. I am having RPM fluctuations while car is at idle, I also notice while driving the car jumps of around 500RPMS if i take my foot off the accelerator and when i depress it. It almost feels like the car will stall if i would be driving at lower speeds.
After researching the problem, i read that carbon and gunk on the IAC and Throttle body causes idle issues(after toyota dealership failed to propose this as an issue i changed my distributor cap, ignition coil, spark plug and wires). Since im not a professional, can i clean the throttle body and IAC hole with carbonetor cleaner without having to remove the whole thing? Does the carbenator cleaner damage the engine? How would you suggest i proceed.
Answer Cleaning the IAC valve without removing it may not work very well but you can give it a try, remove the intake hose from the throttle body and spray the inside with the carb cleaner, clean the inside with a nylon brush, You can also use a can of air intake cleaner available at autoparts stores.
