Gas Engine Specific Aid

Fuel Squirts out, in a steady stream, of Electro-Hydraulic Actuator when starting and running. Then, the fuel that is squirted out, flows through a manufactured hole in the Upper Intake Manifold. Ultimately, the fuel runs down into Lower Collector.

Never did this before winter.

What's the deal?

I am having trouble with cold running and now with running period. Starts fine and stumbles until warm. Changed ovp with new one-better but not much, changed O2 sensor with NGK model-initially better but now appears lean when running above 1500rpm-stumbling. O2 appears to be working. Don't have duty function meter. Stumped. Coding but do not have code reader. Going to get one. Ecu temp sensor resistance supposed to be 250 hot to 2000 cold but that does not jive with charts I have seen. 260 to 300 hot. Very inconsistent cold.

Have an intermittent problem when starting this car. Car starts without problem 70% of the time. Instant ignition, idles perfectly, impossible to tell if engine is running. Other times the starter must be engaged for ten or more seconds before the engine even tries to start. Sometimes 3 or 4 attempts must be made before the engine fires. When it does finally start at these times, ignition is slow and it seems to be firing one or two cylinders at a time before it finally catches and idles properly. Problem arose immediately after having a new fuel distributor installed.

n/a 1984 380SL- bought car with seized engine, replaced with 60K engine from 85 380SE, new rebuilt trans from MB. Installed new fuel pump, filter, plugs, wires, cap, rotor. Engine starts great, rev's great, put in gear and accelerate slowly,and every thing seems ok. Accelerate too fast and engine will stall or start missing. It will get up to speed and seem to run fine, although it feels like it has a slight miss. Come to a hill and it starts missing very noticably but will maintian speed. Car will surge when on cruise control, I assume becouse of miss.
