98 hx z6 head obd2 -> obd1 conversion harness with a p28

ran fine for the past few weeks

just started running like poop latley... its always thrown code 41 (o2 sensor), but just recently in the past 2 days it has not been starting for me... it will start and just die and sometime just crank and not start.. when it does start it will idle really low with a missfire and if i give it gas it will die down... if i give it full throttle it will just stay at the same rpm but verry lumpy and at 1/2 throttle it will act normal (rpms will rise, sometime with a missfire sometimes with out)...

its throwing codes 6, 7, 10, and 41... a few times ive unpluged the ecu for a couple of seconds and it started up, and ive also tired a diff ecu with the same results

once it gets up to running temp it seems to run ok but if i turn it off for more than 20 min it seems like it does the same thing

anyone out there ever have similar problems or experiences like this?

 

If I were u I would put a new O2 sensor on and go from there, cause the bad O2 could b the reason for the other codes bein thrown

 

check timing.
