1984 Toyota Pickup 4 cyl Two Wheel Drive Manual 182000 miles
I just turned this 1984 with the OEM 22re fuel injected motor pickup into a roadster. After I redid the exhaust, (added 2.25" exhaust, Pacesetter header, 2.25" in/out catiletic converter, 2.25" in/out x 36" Trush glass pack, and remounted the OEM oxygen sensor in the pipe about 14" after the header collector) now the check engine light comes on when you run the truck at about 2000-3000 rpms for over a mile. As soon as you rev it up, or down shift the light goes out. Then if you stay at the same rpm (2000-3000) again it will come back on again. I am wondering if I don't have the sensor mounted far enough down into the pipe, or to far down into the pipe???? Would it pay to try an aftermarket sensor? When I get it fixed will I have to get the computer error codes cleared out for it to pass emissions? FYI, the problem came up before I redid the intake, and the intake is only changed 'before' the mass air flow sensor box. For that I just cut the filter housing off the top of the mass air flow sensor box, and welded the new filter housing on top of it.
