I recently swapped a 22RE from I beleive a 87 or 88ish Toyota $ runner into my 91 toyota pickup. I used to get about 450/500KM (even more) to a tank of gas, now I get barely 300KM. I get an engine light that comes on and off again and the vehicle is clearly burning very rich. The timing was done when the motor was swapped in, as well as all the seals on the motor. What do you guys think?? I am leaning towards O2 sensor but I am not sure??? Thanks.

 

Hmmm can't really get the codes pulled to easily? Should the O2 sensor on this model be $300+ Canadian??? seems high?? could the parts guy be on drugs?? Does anyone know what the Toyota Part# is for this particular sensor?? Could the older block with the newer vehicle componets affect which sensor i need??? Or could this be why the fuel economy is poor in the first place??? Thanks. (sorry I am kind of inept)

 

p.s. the light comes on and off so it is hard to get into the shop when it is on. Or do the codes stay stored in the memory???? Appreciate the help.

 

You can get NGK or Denso O2 sensors from sparkplugs.com for fairly cheap.

I am having the same problem with my 89 toyota. The check engine light has never come on but i put a new 22re motor in it and i am getting like 15 mpg. I cant find a problem. Also, doesnt seem like it has very much power.
Need help

 

I just put in a new top end and I have an O2 light on. I was burning off coolant when my HG was bad, and I've heard that can zap the sensor pretty quick. Plus, it's been forever since it's been changed.

x2 on the NGK or Denso. Should be under $100.

 

I checked my codes and nothing came up. It runs really good but i am very dissatisfied with the performance. Any more suggestions?

 

I would probably say 02 sensor, but without codes its impossible to know for sure.

 

Hell, my truck only gets about 220 miles off a tank.

 

Well, $300 does seem like a lot, but with the currency differences from US to Canadian, it's hard to say. I'd say that it is possible that your part's guy might be on drugs. The wacky tabacky is legal in some parts of Canada....

 

My truck is timed with the circuit jumped. The idle does drop when jumped and i just set my valves. There is no cat on it.

 

haha true true thanks I think I'll just slap the denso O2 on there and go from there. Thanks LATER

 

I think found the prob. with my 89. My front brakes seem to be "dragging" (not spinning very well when off the ground.) How can this be fixed? Do i need new brakes? Any suggestions?

 

Take out the brake pads, they won't drag then.

 

i had a 22re with the cat removed and the milage sucked, i wound up putting on a high flow cat with a bosch heated 02 sensor "4 wires instead of two" and got 21mpg in my 4x4 with 31s and it was about 16mpg before i put cat back on.
