1992 Honda Accord Question: very high idle at cold start



Visitor, 2.2L 4 Cylinder, Olivehurst, CA, March 14, 2010, 18:35

i have a 1992 honda accord with 324000 miles on it, i keep it in the garage every night, each morning it starts at a very high idle around 1500 rpm, then gradually slows, it is a five speed. Do you have any ideas what the problem is?

    theres absolutly no problem there, older hondas do this, it idles high at cold start to help warm up the engine, gradually goes down, every honda ive ever had did that, and yes it is the IACV Idle Air Control Valve, and its clearly doing its job, no worries:)
