22RE FUEL INJECTION ?'s

Howdy gents, i got a 1990 fuel injected toyota pickup 2X4 22RE and ive been through it a little bit and she runs perty good although the idle seems to be a bit off. sometimes it will idle low and sometimes it will idle higher. sometimes but quite rare it will fluctuate a bit. So i ask you, is there a way to adjust the ration to tune it in better? what is the black turnable knob accessable from the top of the engine? What are the two or three vacuum operated sensors on the top of the valve cover?

 

Have you adjusted the timing at all? Pretty simple to do on the 22re, just need a timing light.

 

My 22RE use to fluctuate at times. Alomost to the point that it was reving itself, only by about 150-200rpms. I had a vacuum leak and also adjusted the throttle position sensor

 

Actually it was a non runner when my buddy picked it up and the previous owner didn't really know what he was doing and he broke the timin cover. So I ended up having to get a new timin cover and I did the timing chain and a few other things such as oil pan gasket vc gasket etc..... Anyway I had to set the timing so that should be good. How do I adjust the TPS?

 

There is an adjustment knob on the pax side of the throttle body. Adjust it using a flat head screwdriver.
