Alfa 147 1.6 - erratic idle
I have a 147 1.6 that has an erratic idle, the rpm don't stay in one place and the engine shakes.
It happened after i stalled the car. I was waiting in line with the first gear engaged and took the foot off the clutch. I just noticed the shaking after i got home.
I was in the mechanic and we checked:
- piston compression - 11 bar in all the pistons
- injectors checked - OK
- coils are OK as well
- MAF checked
No errors in the diagnostic software.
Everything is good with the engine, no loss of power, just the idle is erratic and the engine shakes a bit in idle.
Over 1100 rpm all is well.
The mechanic told me to buy a full set of spark plugs since he didn't have a new set to check.
Also told me that he wanted to check the variator assembly to rule it out, that because i stalled the car while it was engaged it could have taken the idle out of point.
Is this possible?
