I competed a complete rebuild of my 1971 1800E this spring and it is stock specification except the the head has been ported and comprssion ratio reduced from 10.5 to 9.5:1. Otherwise it is running the D-spec cam. The first 500 miles of use were for break-in. I have installed a wide band O2 sensor to run trails. I've done all the background tests on the temp sensors, MAP, set the idle fuel cut off switch. Fuel pressure is at 28psi. I had the injectors flow tested and they all all good (38 lbs). Engine starts and basically runs well, with two exceptions 1. idle mixture is too rich, 11:1, so very lumping idle and difficulty maintain idle speed (tends to load up). I have the ECU idle adjustment all the way lean, counter clockwise and is will respond to adjustments but it only get's richer. 2. When I run the engine WOT it will go lean, like 15:1 or 16.1 above 3000rpm. So it lacks power.

I've added fuel pressure up to 32 psi and it may slightly help at higher rpm's, but then the idle is more rich than it is now.

I've adjusted the screw in the MAP sensor, but it is currently all the way out. If I turn in, which is the lean direction, it does help the idle mixture, but then the car is 17-18:1 AFR and will hardly accelerate. MAP sensor is 430 ohms and holds vacuum.

So what am I missing? How can I enrichen WOT and not enrichen it at idle?

Thanks.Rick
