I have a 1989 764 GLE. It has an automatic transmission and a B280F (That's a late V6 PRV to everyone).

Engine surges. Says this is simple and likely an oxygen sensor. I have receipts from the previous owner from a Chevy place. They replaced the AMM and fuel pump. I've replaced the fuel pump with a Bosch, and the FPR. I've checked the IAM and cleaned the throttle body with a toothbrush. Something tells me that's not all that's wrong with it, lest the Chevy dealer replace it... New O2 sensor? $150.

There's also a thousand dollar oil problem. I've basically made up my mind that I'm not going to bother with this and sell it for parts, fix'er-up, demolition durby, artificial coral reef, whatever. I'm going to see if I have a recept for an oxy sensor, then call him back to replace it.

Number one, should I get the oxy sensor replaced? Number two, how much should I sell her for?

Measure the output of the 02 sensor before you replace anything...

Have a look at NADA.com for book values-- I recently got $5750 CDN for my '89 from my insurance co after spinning out on black ice at 80km/h, leaving the road and hitting a tree...

I've thought about hitting a tree with it, but I wasn't sure if the clockspring was still in good shape. I'm not going to put the money in it. The money I spend to fix this girl up will go a long way torwards the 940 or 850 of my dreams.

The car has not been in an accident on my watch. I can't account for the previous owners. I'm highly drawn to the later 940's, however my signifigant other demands a sedan. She prefers the 850's over the 700/900's. Of course, she drives an american made cute-ute.
