Car is not running hot at all idle is a little rough and sounds like I have like an air rumbling sound coming from my engine

My service engine light comes on and flashes rapidly, then the motor starts missing then motor quits , I put a diagnostic tester on it and it shows mutable sensor failure. did this ten times and it was never the same sensors showing up ,everything is random. I'm out of ideas .

problem as theres no sign of tranny problems. help, I need my car

My heat and air barely work. The only time they do work is when I'm going more then 40 mph, and then they still don't blow enough to heat the whole car.

once I slow down to make a turn, whats the problem

Mass air fault came up rr new ran worse got another new ran bad also put old back in and drives fine except shuts down at stops any thoughts cause code keeps saying mass air flow sensor

I was leaving for work this morning and the power to the car just quit. the engine is running but when i press the gass pedal rpm goes up but nothing. been outside testing it the transmission fluid is fine and oil. the engine is running normally no sounds except basic engine noises, however when i put it into gear it sounds like the engine is trying to stall out, I watch the battery volt meter go back and forth and not sure what could be causing it. again when in park or neutral the engine runs fine but when i put it into gear it sounds like it trying to quit.

I drained out and replaces all rear lights and don't know what to try next...

I read my manuel and the parking brake has been release but the light stays on

Someone told me that the drivers side door module needs to be replaced and he said it was going to cost six hundred dollars does that sound right?

interior lights and sunroof do not work either. happened all at once parked car came back a week later locks, interior lights, sunroof seem to have no power

Ive tried everything turniing the key on fo 10 minutes to reset,lock the doors with remote and unlocking with key,tried tieing cables together for reset and security light still flashes and car wontstill wont start
