We just bought a 2000 Odyssey for a second vehicle because it ran like a champ and was in great shape...107000 on the odo.....now we've had it a couple of weeks and just got a CEL and a P1457...cleared that...then a P1457 with a P0420...cleared those....then a P1457 and a P1399...all within a couple of days only driving it a few miles. Now today it smells like fuel and is idling like a tractor! I've researched the codes but there are a 100 different opinions...so where do I start? I'm mechanically inclined but this is a lot to take on at once...thanks!!
