Bills 86e, I didn't need to open up my DME. My problem ended up being a partially clogged radiator. It flowed well enough to cool the motor as long as I didn't get caught in traffic, but it would not...

I meant that normally jumping the brn to blk/grn wire will turn on the low speed fan.
Try using a jumper wire from the switch to the relay as I previously suggested. You should at least have a...

Since the circuit diagrams that I have seen only show the ECM (DME) as essentially a black box without imput from the ECT it is hard to know how a bad ECT might affect the system. However, jumping...

In my experience, the catalyst efficiency code may also come on when you need a new upstream O2 sensor. It is possible that you are getting that code because of an air pump problem.

While between the lines might not ruin anything, why start out down on oil? I would be pissed if I paid someone for an oil change and they only put in one gallon and left it a half liter down.

Your oil level should be at the top line on the dipstick after you run it to refill the filter housing.

Driving the car at 80-90 mph should not be at all bad for the car (excepting the obvious dangers of a blown tire, road debri etc etc). Not checking the oil between oil changes on a 12 or so year old...

1) You definitely should be checking your oil more often than every 2,400 miles. It is a very good idea to check every time you fill up the gas tank.

It sounds like you mean that there is infinite resistance between the black and the blue leads. That does sound like the resistor is bad. I don't know where you can find one new, have your tried...

Could be a problem with the wiring or connector for the sensor rather than the sensor itself. Too bad it is so hard to get access to the connector.

Check your engine temperature. Thermostat failure shows up as lower operating temperature which will result in a richer than needed mixture and lower gas mileage.
