I wanna be sure before i buy new one. 2003 taco 2.4L 2wd 5sp 73k miles(not a typo)
2003 Toyota Tacoma Factory Service Manual page SF-25 says 2-3 ohms at 68°F and 0.9-1.3 ohms at 104°F. I get 7.3 ohms and 2.98 when probes reversed at 90 degrees F. New meter.
I don't think dirty MAS would read high, would it? OK, I just sprayed it liberally with 70 percent alcohol and let it dry. Readings unchanged. Taco runs the same.
The symptoms don't point strongly toward the MAS. More so a dirty TB. I just cleaned the TB and IAC w/o removing from vehicle. First time cleaning since i bought taco new in 2003. So, yea I might need to remove to do a better cleaning, but before that I decided to test the MAS. This vehicle drives fine! Just idle sometimes slow and sometimes fast. Slow is more common, then fast. Idle always goes way low when release throttle. It usually recovers, but does stall once in a while, more so with AC on.
tks,
