Code 25 and 26

Murd · 10-04-2006, 10:05 PM

*revives dead thread* My car started stuttering on acceleration and running rough on idle. So I did a diag, and pulled up codes 25-26. Running to rich, and too lean. Anyway I searched the board and found this post. Before I tear into this and replace the seals on the injectors, is there anything else I should do or check while I have em out?

What I did with my injectors while they were out was to power them open and use a can of carb cleaner while they were open to clean them out. You just have to take a spare plug with a couple of feet of wire and hook them up to a battery to energize the injector open. For the carb cleaner use the kind that has the straw and wrap a little tape on it so it seals at the injector opening and spray till it comes out in a good pattern, usually only takes a few seconds. And by al means use goggles when you do this so you don't get any in your eyes!
Also a faulty ox sensor might cause this too.

If your injectors are messed up and spraying too much or too little fuel each time. Or if your o2 sensor is bad, like stated /\

OK it's been a week, and AutoZone hasn't shipped my parts, mainly the Injector O-rings... GRRRR!!! Anyway, my wifes car crapped out on her, so just to have something running I put mine back together, I found a vaccuum line disconnected when I was pulling it apart anyway so had some suspicions. Got it all back together and the only thing I really replaced was the plugs, and the rotor <cap, wires and o-rings not shipped>. Ran a diag, no codes all clear. Drove it around for about 20 minutes, rechecked codes, no codes all clear.So it looks like it was a vacuum line causing the issue. I'll keep an eye on it and keep you posted on how it's running. Anyway just wanted to post a followup post about it.
