Got a convertible

I picked this car up for almost nothing. It actually runs good, it is a 3 cyl automatic. It has A/C and a bunch of other crap in it. I am probably going to rebuild it and lighten it as much as possible. Once I…

Oil Pan

panThe windage tray was not hard to install, Just cut the old factory tray out if you want and stick the  new one in place. Test fit it and make sure it clears everything then weld it down in a few spots.

4 Wire Oxygen Sensor

The factory one wire Oxygen sensor works well for what it was designed for but it does have limitations. 4 wire sensors have been used for a while so it is easy to find them at junkyards. It is easy to test a sensor to make sure it is working with just a voltmeter and propane torch. Take the sensor you want to use out of the car and hook your voltmeter up to the sensor wire and sensor ground wire using the chart on this page to figure out the wires. Once you have it hooked up you should be reading 0 volts. light the propane torch and hold the tip of the inner blue cone on the oxygen sensor. It takes a few seconds to get it up to temperature and you should see the voltmeter go to .9-1.4 volts. Once you get it there twist it around to make sure the whole element is heated evenly and any buildup on it is burned off. The voltage should drop within 1-2 seconds to under .1 volts when you take the propane torch away. If it does not go down quickly then try turning the propane up higher and burn off any deposits on the sensor you can. It will not hurt the sensor to make the case glow orange. After a few minutes of cleaning the sensor it should respond quickly to the torch being pulled away from it. If it is slow to respond to the torch being added or taken away then it is probably lead or silicon fouled and you can give up on it and go to the next one. If after 5 minutes it isn't working like it should then give up on it and pull another one off a different car in the junkyard. I would grab an extra one while I am at the yard just to have a spare they are cheap.
