has but he has an error 16, with mine it has 20. (my car isn't flooding.) when i go the speed i need it at, it could stay there, but still have problems with the beams. also had a speed sensor error code 17 for awhile, got these codes when i went 50 miles. Please help asap!!!!!I'm ready to strap a couple pounds of c4 to it and blow this car up.

 

my crx did this, it was the altenator

 

the alternator puts out 12 volts so it shouldn't be that.

 

mine put out 14 volts but i changed it and it fixed the issue

 

Alternators are supposed to put out between like 14 and 16
