Do you ever have days like this?
The old Mazda B2300 has been running rough after the first few minutes. Restart it and it runs good the first few minutes again. Code said the first O2 sensor probably bad. Seemed typical of a failing O2 sensor. Only 20 odd bucks so I bought a new one. Never replaced it in the 18 years I've owned it so I figured it was due anyway. Thought it may have been oem from 1997... more to come on that in a minute. Grrrr.
First I need to pump up a couple tires to move it. Get the mini tire inflater out of the car. Pump up one that is only a bit low, fine. Get 24 psi in the flat one.... little compressor dies. No biggie, enough air to move it near my main compressor.
Drive it to a level spot and begin to jack it up.... %^&$#@ tire jack blows a seal. Drag out a bottle jack and finally get it on the stands. Beginning to wish I stayed in bed.
Expect the sensor to be about impossible to remove. Pop it lightly with a 7/8 wrench and it breaks free. Starting to feel better about life in general. Squeeze my hand into a space a 10 year old child ought not have to reach into. Start unscrewing it by hand and the darn thing is loose. Actually wobbles a bit coming out. Either someone ruined the treads replacing it previously or the threads erroded away. IDK. Waste 2 hrs trying to install the new sensor. No dice.
Give up and decide it must go to a mechanic. Probably have to remove the exhaust header to fix it.
Crank it up, As expected, loud as heck with the open bolt hole in the header pipe. Let the motor run 3 or four minutes and it goes to running rough AGAIN. So it wasn't the O2 sensor to begin with. Now I gots the roar of a P52 Mustang on top of the skip.
I go in the house and the wife asks how it went and I reply:
" Honey, I'm sleeping on the couch tonight. With the luck I'm having.... I don't want to risk breaking anything else tonite" :tantrum:
