Well boys and girls I got my car back with one new coil today and it ran good except it was stumbling a little bit. So I thought I would decide to got to the bank get some money and get new NGK spark plugs. Guess what on my way to the bank my check engine ligh came on. Well instead of being like damn, I was like yes a chance to use my scanner and see if it works. Well it does and damn good. Checked my code with the OBD and it read the number and problem, misfire in cylinder 1. Ran rite back to my dealer ( I live down the block from my Mazda dealer) to show them and they ordered me another one and said it should probally be in by friday to come back and that it should be alright to use my car, but I wont unless I need too. But that is not the end, I decide to play with the scanner and I can also monitor the engine why its running. This thing is great, I can read o2 sensors outputs, RPM, Seedo, intake air temp, water temp, ignition adv. and so on. So I wnet driving around a little and this is what I found, Intake air temp is like 40 - 43 degrres C at idle and about 23 C moving. Speedo is on point to the tee. I found that my tach reads about 150 RPM's higher at 2 1/2 to three ( I didnt stay at a constant RPM to higher then that on a constant basis to give any other RPM readings rite now). This thing is real good. When I get my new coil in I will put my intake on and tell yall if my intake temp changes and by what.
Peace
