My trouble codes! Yesss...
Posted: Fri Apr 25, 2008 8:52 pm
Okay... so the weather was nice today, and so I decided to check my codes. Left the battery unhooked for 15-20 minutes before hand.
22, 23, 24, 49
First thing that seemed strange is the 49. Wrong airflow sensor? This only came up after the day I changed my plugs and checked the MAF. I tried to start the car a couple times after forgetting to plug the MAF back in and it died, naturally. I plugged the MAF back in and next time I checked the codes, 49 was in there. That was about two months ago... and the code hasn't gone away.
22 and 23 have been around for a while... still trying to figure out how to resolve those without spending too much money (and the knock sensor is really hard for me to get to with the TMIC in the way). Could 23 be related to the new 49?
24 is new(ish)... I don't actually remember how long ago I noticed it. I do notice that when the car drops down to 1k and below (at rest), the RPMs aren't steady. My Haynes says the IAC valve could have an impact... which makes sense.
Also, when out of gear, as the RPMs drop to and past about 2k, I hear a strange sound from the exhaust, almost like when you light a butane torch (minus the hissing).
Lastly, my mileage is pretty bad. I was getting around 12mpg when I would lug it around town and only hit it hard every once in a while. I replaced the fuel filter and the air filter recently, and now I get about that driving the car a little harder, and I actually hit 15mpg on the last tank, where I drive conservatively for a couple days and then went out in the dirt for fun a couple of days.
Advice on what to do would be appreciated! Thanks for reading, anyway.
