The other day I had a RENAULT MEGAN 1600 16V Customer complaint that the
car is cutting out when she go around a corner or when she approach a red light. or stop street.
She could start the engine immediately and would go on without any troubles.
I took the car for a test drive and found that the car is not pulling strong, as if one of the
ignition coils is not firing. There is a lack of power. The engine would sometimes cut out at
stop street or if one go around the corner. Pulling away also was not smoothly.
To cure the problem I have done the following:
1. I have removed the ignition coils and test them on a tester , they test all OK
2. Test the fuel pressure it is OK.
3. The next thing I have done was, I noticed that the MAP (manifold absolute pressure) was very loosely,
as if the "o" rings were worn. I tried removed the MAP sensor but the front part broke of and I had to
remove the front part from the intake manifold. Once I got it out I use super glue to reassemble
the front part to the MAP body.
4. Diagnose test show no codes, so this makes it more difficult.
I took the car for a test drive and it performed much better, the engine is not cutting out anymore and
performance is back to normal.
The MAP sensor must have been cracked just above the "o" rings causing the engine to cut out and
cause the engine to perform poorly.
