e46 323i Not running right
My car is a 99 323i, its an automatic with 200,000 miles. When it is cold it takes forever to get warmed up, and while its warming up it idles rough and dies a lot, and after warming up it runs almost perfect. I had the codes checked and there are a ton of error codes. they are
p1750 Secondary pressure solenoid p1751 Secondary Pressure Solenoid p1748 Transmission control module self test p1749 Secondary Pressure Solenoid communication error p0705 Transmission range circuit p0727 Engine speed sensor circuit No Signal p0731 Gear 1 Ratio incorrect p0734 Gear 4 Ratio incorrect p1747 CAN Bus Monitoring p1748 Transmission Control Module self test p1770 CAN Torque Interface P0705 Trans Range sensor circuit malfunction p0753 Shift selenoid A circuit electrical p0758 shift selenoid B circuit electrical p0763 shift selenoid C circuit electrical I recently replaced the battery, spark plugs and fuel filter. I also had the transmission fluid level checked and it is fine. the trans shifts just fine. Im thinking it might be something electrical. can anyone give me some advice as to where to go from here? |
