Trying to help a friend ...The Brick is a '91 245.
I did a quick once around so it might pass emissions now BUT if it doesn't, where do we look next?
I don't have the previous emissions numbers but here's what we did to the car.
Fuel pump regulator; Seemed bad,wet hose; we replaced it
Throttle body; Dirty, took off and cleaned. Switch was set correctly.
AMM buzzed out at 3.5 ohms between pins 2 and 3. Bentley says that's a good AMM
Big Bellows: no holes and not to gacked up at all, so that's OK
O2 sensor replaced. Can someone run through the test for that? The more I read the more confused I got. It's a 3 wire type. What gets disconnected and what stays connected. What do I check to GROUND?
New plugs, new wires and new Rotor/Cap.
Idle Control Valve was taken out, jumped with 12V and it snapped back and forth nicely. So that seems OK
Flame trap was cleaned. Ohhhh, I didn't check the nipple. The small hose was clear, don't know about the nipple to the intake though.
The ECU; they don't usually die this way from what I read. They usually just die. Is that correct?
