Loosing spark?
« on: December 04, 2018, 03:51:23 PM »
Hello Everyone.

My first post here, but following for some time.
Now came to my turn asking questions.

What I can't figure out is that it happens shortly after turning (more often right then left) that engine stops recting for accelaration pedal. It seems like a spark problem, because same thing happens while running with lpg. After a couple of secs runns normal way. Some times happens to have rough idle. Some times very high idle RPM like 1500-2000. Comes to normal idle when kick the pedal once or twice.

It's an m44 with m42 loom and ecu. With replaced front cover and m42 cam sensor and sprocket. With coil on plug. All intake hoses replaced. Tps replaced.
For this moment no coolant temp sensor, doing 2in1 conversion but happened also before with sensor plugged in.

The only thing I did not look into is the crank sensor but asked the mechanic to check if there's no wiring problem and got reply it is all in place.

Appreciate any advice.
BR

Another thing is it seems to run rich. As per inpa, oxygen required is out of range. Same for fire angle.
What's more coolant temp with no sensor indicates some values not -59C.
