Toyota trouble, O2 sensor?
A while back my trusty '85 toyota pick up ( 22re EFI ) began to exhibit a strange lugging at low RPM's when excellerating from a stop. Soon after, the
RPM's would drop suddenly at highway speed...but only briefly. Now suddenly the truck won't make it out my drive. It lugs and stalls. Stepping on the
gas seems to have no effect on the RPM's, which never get very high before the engine dies. Some have suggested this is the oxygen sensor causing the
problema. Can any toyota fans out there give me some ideas? Is the oxygen sensor easy to get at and replace my self?

22Re
Fuel filter?
When was the last time you did a complete tune up?
Plugs , cap, rotor, check resistance of plug and igniter wire, fuel and air filter.
What's your ign. timing?
Have the same exact thing in the middle of my shop floor right at the moment

I had a similar problem with my 86 22r. It was the fuel filter. Incidentally the only other problem I had in the 9 years I owned it was a fuel
pump.

Thanks for the suggestions all. I will investigate the fuel filter and other possibilities suggested by Bajalero.

I also am having similar, but not to the point where it won't run, problems with my 22re.
Besides the fuel filter and oxygen sensor I have been told that it is also possible for the catalytic converter to clog up and exihibit similar
problems. Maybe it's time to take it off or rod it out. If it has to get smoged in the US don't remove it.
The fuel filter is the hard part to get to.

VERY doubtful that the O2 is the problem......
fuel filter and fuel pump( pressure ) are at top of list.....how old is the pump? start there before you throw a bunch of parts on.....(average
life span of pump is 75-100 K miles or around 7 years )

Thanks for the input everyone. For the record, the fuel pump was last replaced back in the early '90's and many Baja trips ago. I remember when the
old one gave out...it happened all of a sudden and just shut me down roadside right away. That's why I jumped to other conclusions with these new
symptoms.
Thanks for the links Grover!

No matter what I would do the pump now....I replace mine around 90 k just for confidence....(when/if they make it that long)....better to do it at
your choice than side of the road when it decides to stop....
is your pump in the tank?.....

I assume it idles OK out of gear and the gas is good. First get a code from the flashing check engine light and see what that tells you. If no code
check the fuel pressure 33-38psi. Low pressure replace filter or check it with the filter bypassed. If the fuel pressure OK. Check the ignition system
and for air leaks. Eleminate things one step at a time.

When the O2 sensor is not working the computer just goes into closed loop and does not look to external sensors for input. O2 sensor will cause
milage loss and drivebilty problems with change of altitude and temperature. Fuel would defenitly be where I would look first. The fuel filter will
make you take back every good thing you ever said about Toys.

On my 91 chevy I had to change the fuel filter every 25,000 miles. The signs were it would lose power around 2500rpm and start spitting and
sputtering. Below that it seemed to run OK. On my 93 Toyota I changed the filter at 100,000 miles just for the heck of it. I drove them both in Baja a
lot but why the difference in filter changes ??? maybe the chevy throttle body injectors required more pressure.

At the top of the Throttle body. (front top of engine) there is a idle adjustment screw ( Flat screw in a hole) I t has a o ring on it and if that
cracks it could cause that problem
Good luck
