Hello everybody,
My name is Chris and I have a 1993 FZJ80, 255k on the clock, purchased 2 years ago at 225k. The truck has a long history of being neglected, and I have been putting it back together for the last couple years.
Recently, the idle started to s*** itself. Under load things would be fine, but in park or just idling the truck felt like it was shaking. After about a month, it became a consistent code 26(rich) along with symptoms. At this time, I also started to lose power and the truck began hesitating.
Fast forward to today, I had tried a couple things to fix it, and the only one that worked was replacing the original??? toyota O2 sensors. Very strange to find something that is not chinese on this truck. So I think they may have been original. The only thing that helped the idle while I was waiting for the sensors was unplugging them. It seemed to go back to normal(What the truck has always felt like).
I also... wrapped the harness at the EGR(was beginning to melt a wire), checked grounds/vacuum hoses and whatnot. Everything looks good.
I sourced some of the NTK O2 sensors, removed the old ones and installed while cleaning out the the plugs(historically every tie it rained it would **** up the outer sensor, I now wrap it and grease it).
Pulled the EFI fuse and for the first time ever, the car did not begin by pushing the RPM's up to 2k. The truck has always smelled like a gas station, burned fuel or oil(not sure) and was running rich.
After the first test drive, code has vanished and was much more peppy, no hesitation, and no s*** idle. I was very happy.
2 days later, everything still feels fine, but the truck is throwing a code 25, lean. I know that a lean condition is not good for your engine, and has me concerned.
As far as truck history, it was a cartel truck(found a loaded gun in the bumper and got it in San ysidro San Diego) and I have touched almost every system. Not that everything has been replaced, but something has been adjusted or touched from pretty much all systems, so I just don't want to list everything.
I keep reading about PAIR valves and whatever the (not a MAF) is called. Originally, I thought I was having a fueling issue until I found out he O2's were shorting and replaced em.
Thanks guys.
