I've been using this page for years but decided to join since I really need some specific help...

CEL was on. Code was P1035 (o2 sensor, after cat converter). Replaced it with Bosch universal rear o2 sensor. Cleared code drives fine but CEL back on w/same code. Here's the snag, I can clear the code and first start after clearing there is no CEL, second start and CEL comes on.

Here's the details of the scan;

Fuel Sys 1 - OL
Fuel Sys 2 - CL-fault
Calc. Load(%) - 30.98
ETC (Farenheit) 140 degrees
STFT B1(%) - 0.00
LTFT B1 (%) - 6.25
MAP (in Hg) - 11.52
Eng RPM - 824
Veh speed - 0

Anyone got ideas? Klaus?
