Can anone tell me the procedure for setting the Duty cycle on this 260?
The Landis site is kinda vague, and I want to be sure we got it right.
The car runs better now, but has hesitation when you snap open the throttle... almost feels like a misfire.
Maybe we can post a video of the throttle plate when it does this....

We are gonna change the plugleads and cap/rotor , idle and vac pipes arrived too, so by the weekend we will have all the normal stuff done.

i remain corrected, the egr system with the air pump and egr valve started in 1991 which is the year of my 190E 2.6 which is interesting. Emissions until 89 was controlled by lambda.
