RE: [DML] O2 sensor damage?

["Scott Mueller" <scott.a.mueller@xxxx>]

I had to replace my ECU when recommissioning my car.

Perhaps there is someone local to you that will allow you to swap there
working ECU into your car for testing. As I recall, the ECU was a few
hundred $.

Also, I recall that someone on this list or one of the others offers a
service to refurbish ECU's

Can you ruin an O2 sensor with a super-over rich condition or with 
excessive heat, say from a glowing cat?

The dwell meter on my car says the lambda computer and hence the freq 
valve are not operating properly.

Since I've been told by multiple sources that the ECU almost -never- 
dies, the O2 sensor is the most logical next item. The problem is, 
mine's nearly new. I did have it installed way back when my fuel 
system was totally hosed. I got the cat converter to glow cherry red 
a few times.

Thanks,

Rich
