Sucks, I know. <img src="/forums/images/graemlins/pfft.gif" alt="" /> Itsa '94, 22-RE and I'm getting code 25 - lean mixture. Manual says it can be caused by many things, some of which are bad O2, bad MAF, bad injector, bad fuel pressure, etc etc and etc. Any tricks on how to narrow it down? The CEL comes and goes now and then. Don't tempt me to swap it to carburated, cause I will <img src="/forums/images/graemlins/smile.gif" alt="" /> Thanks, Scerb http://www.scerbfab.com/carb_faq.html Re: code 25 - lean mixture [Re: Scerb] #827850 07/31/07 02:17 AM Joined: Sep 2004 Posts: 1,015 ChrisH Body Damage is Cool THIS THREAD IS USELESS W/O PICS DOT JPEG DOT GIF '95 Toyota Pickup DX Xtended Cab ~ Daily Driver Re: code 25 - lean mixture [Re: Scerb] #827851 07/31/07 02:18 AM Joined: Jan 2000 Posts: 12,153 N.
