I've got a 2020 axis t22 with a M5di engine, just got it delivered brand new this march.
For the first 70 hrs, the engine ran like a champ. Then it got to a point, when it start to stall for no reason when i am accelerating from idle to surf speed.
It happens at around 1500-2000 rpm during acceleration to surf speed (which should be around 3500rpm), the engine just cut, then the service engine and MIL comes on with a long bee alarm. Then I just turn the key all the way off and restart, and every thing was fine. There are times that this happened 10 times a day and there are times that it ran all day with no problem.
The fault codes I found was inactive:
spn 4237 fmi 0
spn 4239 fmi 0
So far, I have my O2 sensors cleaned, fuel filter changed, fuel pump filter changed trying to solve this problem, but it still continue to happen at random.
Does anyone have any idea about this? Any suggestions would be helpful, Thanks.
