2.4i ECM250A

Post by bobbik » Sat Sep 07, 2019 12:21 am

Car is not huge mileage -130K km but wasn't ride last three years. I changed oil , brakes , etc.. and about 1,5K km everything worked fine. After that MIL lamp appeared. Vida throws ECM 250A lower limit.

# I've checked vacuum at brake booster line- airbox connection, was strong, so Venturi pipe is in good condition.
#Rubber elbow between oil trap and manifold is ok.
#Long accordion pipe between valve cover and oil trap wasn't ok, but i fixed it.
#MAF cleaned , and shows about ~3.6 at idle, is ok.
All adaptations cleared with Vida, but MIL came on almost instantly (after few km)
I didn't checked diaphragm in oil trap, but I can't hear any squicky sound reported by others, who had broken diaphragm.
Any other ideas?
