    My 1991 Honda Accord runs fine in the morning drive to work (6AM) but after driving home late in the afternoon when the outside temperatures are 95-100 the idle speed surges to almost 3,000 and then drops back to almost 1,000. It keeps doing this until it is shut off and allowed to cool off. Could this be caused by the water temperature sensor sending wrong readings?

IAC valve. Your Idle Air Control valve has gone bad. This is an extremely common problem with these cars. I had one in my shop with the same problem yesterday.

There is a coolant passage that goes to the idle control system. The idle control itself is not bad. Cleaning this passage will make it normal again. I have fixed a 95 honda accord this way, and a 97 honda accord. You will need to remover the whole assembly. Actually the whole rapair doesn;t need parts so thats good news for you. Be carefull since the idle control is made of aluminum, and can be damaged easily. I damaged the one I was working on, thankfully I also have an aluminum mig welder so I was able to repair it like new.

Idle will not come down


check for vacuum leaks, that will typically cause a high idle.

Very low idle speed.


You may want to check your Throttle body position sensor (TPS), and/or, the idle air sensor. This is the most common cause, and in some cases, if your car is acting funny more than at just idle, your Mass airflow sensor (MAF) could be fouling.
