Running rich help
Posted by Lester [Email] (more from Lester) on Wed, 13 Feb 2019 07:09:46
Hi all, my '96 9000 started running rich, REAL rich, like backfiring with sooty tailpipe rich. A quick check with the Tech II and I see that the fuel system thinks that the car is running lean and has gone full rich adding extra fuel.
I have the Tech II but not sure what to look for. My thoughts are:
O2 Sensors - what spec should they be?
Coolant/cylinder head temp - IIRC I get a voltage readout which doesn't help me
What say you all?
