i took my car out driving for a while and when i was driving something started to happen and i looked at my turbo timer and it said i was running rich and it felt like i was having power loss and lots of backpressure.... and i looked at my voltage on the turbo timer and it said i wasnt charging and i just changed my alternator... and when i get home the car was idleing really rough and low and it was making the car shake and something weird happened it sempt like it would go back to normal when the clutch was in... next day i was able to start up the car but it was still idleing the same rough and lowwhen the clutch is in but when i let go of the clutch while im in neutral my car dies everything dies if the clutch is not pushed down... its a real pain now and i tried everything to fix it... any suggestions wut to do
