So I've noticed recently my idle has gradually become worse and worse. I don't have an issue with it hanging but the opposite. It ran fine when I bought it and idled smooth. I have the K&N Ram air intake kit for starters which I have read could be involved, although it was installed long before the issue ever occurred.
My idle has as of late when cold idles at 1000, warms and will usually idle at 700-800.
Well now it idles at 700, and after about 5 minutes of continuous idling, almost like clockwork, it will become rough bobbing inconsistently from 700-500 and at some times down to 200 almost stalling. I have had it stall at idle once, and also while rolling into a parking spot twice with the clutch pressed in and in neutral.
I cleaned my maf, throttle body, and IAC valve, as well as tested the valve based on the ohms reading it gave. The test sheet says it needed to read 7-13 ohms otherwise replace it and it registered 9.5
Also changed the fuel filter too on a side note. I tested the battery, starter, and alternator as well to rule out lack of power.
What would cause a sudden change in my idle? Nothing has changed in the tune or otherwise mechanically since I bought it 3 months ago and this has recently started. No codes are thrown indicating a bad sensor or IAC either.
Any help or possible list of things to try to rule out would be greatly appreciated.
Just a recap
rough idle 700-500 with low dips to 200 and sometimes resulting in a stall.
