3.0 help needed badly
« on: Jul 06, 2006, 03:05:47 PM »
please help me!!  I have a 91 ext cab dlx with the 3.0. it started to run rough from idle to around 1500 rpm, with a noticable loss of power. I found the #5 plug wire had pulled back into the boot at the distributor and had been arching. so after new plugs and wires, still rough. :mad: :mad: check engine light came on with codes 25 & 26. But how can it be ruinning lean and rich at the same time? :headscratch: :confused: can someone please help me with this.

Are you sure you're counting the flashes right?  :headscratch:  if you are, then I'd guess you may have an ECU problem :dunno:

I'm assuming you have a book to check the codes with, I know my HAynes manual suggest a few different things that could be an issue with each of the codes.  See where they overlap.

The only reference that I have is the link from this site to the toyotech site. And it list the same culprets for both symptoms. My friend who is a ASE master tech told me to clear the codes, and when the light comes back re-check it, and that only one of those codes should show up. Thanks Blackdog, if you or anyone has anymore info I would greatly appriciate it. :beerchug:
