Details on vehicle
1989 260e
no EGR Valve (didn't come with one)

Performed the following approximately 2,000 miles ago:
New O2 sensor
New Bosch Copper Plug plugs
New Plug wires
New Rotor
Adjusted lambda

Approximately 4,000 miles since last oil/filter change

Since failing I filled-up gas tank and added Guaranteed to Pass (GTP)
Currently I am 1/2 way through this tank of petrol

I've read through the various threads on emissions. Any suggestions from the group before I go back for my 2nd test?
