Erratic Idle
Took my 98 dx 5spd to the shop today and asked them to check my IAC.
Which I will check myself. There is some crappy air intake on the car and the people at the shop said thats what was causing my up and down idle. Can a crappy air intake cause the same issue as a malfunctioning IACV? |

An engine needs air in order to runs. If it does not get the air that it needs,it could effect the way the engine runs. You should remove the crappy air intake and visit a auto shop or junk yard place a air intake system on the car that has a new filter. After you do that--take it back to the shop and have them recheck the IAC. You may want to ask your friends if there are any stores that sell after market air intake systems. visit this site: andysautosport.com |

A quick test: Warm the engine up to full hot and keep it running. Pull the "crappy intake" so you can see into the throttle body. There ought to be a port visible in the throttle body. Partially cover the port with your finger. Does the idle settle down? Keep covering more of the port until the idle settles down. Does it eventually settle down? If so, the IAC isn't moving correctly. Do you see TWO ports in the throttle body, or just one? If your car has TWO ports, then the lower one leads to a Fast Idle Valve. This should NOT be admitting air when the engine is hot. If it does, the Fast Idle Valve is bad, usually the result of a sludged cooling system. Also check for other sources of air leakage, such as a vacuum line disconnected. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

Honda premix is the foolproof thing to try first. You might have to top it up to MAX twice. 'Curly' |
