02 sensor please help
« on: Oct 21, 2008, 08:33:29 PM »
i have a 92 4x4 pickup with the stock rebuilt 22re and it ran good up untill a couple of days ago. the problem started on my way to work in the morning. I drove about 10 miles with no problems untill i hit a stoplight and i then realized my truck was idling very low at about 600rpm and missing just basically running like :pokinit: untill i gave it gas and it leveled out at about 2grand so i adjusted my throttle cable to 2 grand to get me through the rest of the day. i changed my plugs and wires, cap and rotor. put all new o-rings and gromets on my injectors and cleaned them up, re-adjusted my valves and rotated my distributor which just increased the missin the more i advanced it. I'm lost!!!! big elk camp trip coming up thursday and my truck :pokinit:s out :shake:. the only other thing i can think of is the o2 sensor. i had pace setter headers on but replaced it with the stock manifold whick leaks really bad and was wondering if anything else would a  lack of exhaust passing the sensor make it runn like ass? or should i be looking in a different place? no check engine light is on my dash so i cant get a code by crossing wires on the diagnostic box. any ideas, suggestions? anyones 2 cents matter to me right now considering my hunting rig might be down for my favorite season of all. thanks

O2 sensors do wear out.

Has it ever been changed?

Don't know if a 92 uses a heated O2 sensor, but I retrofitted a 3-wire (heated)sensor to my 86 and driveability improved.

Mine did this last month.  Throttle Position Sensor was fried.  Runs fine now(though the injectors are still louder than the worn lifters - heh)
