Rough idle and shaking, e90 07 328xi
Hello so a month back I had a coolant hose blow on the upper radiator that also connected to the oil coolant housing gasket, I had replaced the hose and also replace the over flow hose as well. While I was in there I decided to replace the oil housing gasket due to oil build up around it. Since I had everything a part I also decided to replace the intake filter and the cabin air filter as well. So I got everything back together filled up the fluids and the proceeded to take it for a test run it ran great came back home turn off the vehicle the next time I went to start the car the check engine light came on, so I went back through and looked over everything found out the MAF sensor wasn't connected. I contacted the sensor and then engine starts to idle and shake bad! I decided to order a new one which I installed today same problem occurs. I disconnect it and it runs smoothly any suggestions I also have my o2 codes all on but don't think that would be messing with the MAF. Any suggestions or help would be appreciated!
