302Travis Yeah it sucked but has turned out to be a good thing! Because I paid $2900 for it a year and a half ago(it was a steal of a deal). and I'm getting book value paid to me. Which currently is $4075 lol

my_beautious_ZX3 on the bright side, you no longer have a surging idle problem.



sorry about the misfortune and glad you walked away (relatively) unscratched.

sleepyboy Oh man so sorry to hear about that, good to hear your alright. We've had quite a few members walk away from crashes, so the focus has time and time again proved it's crash worthiness. Also glad you took a chevy out at least lol

302Travis We shall never know now. :( dick head pulled out in front of me at an intersection in a chevy colorado. Hit it in the rear axle at about 45mph totaling my poor Focus :( But... SHE TOOK A CHEVY TRUCK WITH HER! lol And a testament to God and the Focus's crash safety. I came out of it with about 4 scratches and a bruise. GO FOCUS!

sleepyboy HERE is the how to on cleaning the IAC

302Travis It surges between like 250 to 900. Feels like it'll die sometimes.

emsvitil When cold, the IAC is probably moving farther than it does under normal circumstances.

It's probably hitting a slightly gunked up section and it's sticking....

my_beautious_ZX3 ^yeah, unless it is momentarily stuck open and takes a few moments to un-stick itself. If it happens every time you do a cold start, unplug the IAC electrical connector and try starting it.

Else, how high do the rpm's surge? Is it dumping fuel - what does the exhaust look/smell like during the surge?

302Travis Well the fuel filter only has about 10k miles on it and so I wouldnt think it would be that. Dirty iac maybe but shouldn't that affect the idle in more cases than just a cold start?

jetrinka Dirty IAC. Plugged fuel filter. Lots of possibilities.
