ok here is my problem. my car is throwing two codes. i scanned them with my diablosport.

-random multiple spark misfire
-air bank system 2

i talked to the dealer about the first one they said it could be many things.im trying to find out what the most common reason. ive been throwing this one for a while.

the second one i have no idea what the hell the problem is, and is new.

please i have faith that some one on here can solve my problem.

Can you post the actual codes? I've had P0300 a couple times at WOT and just deleted it, air system bank 2 might be P1416?

if i rev to 4-5 if smokes really bad. the smoke is blue, i dont think my rings r bad, it just started smoking n i dont think my valves r bad either. it runs real fine @ idle. even if i get on it it is still strong.

OK, one time I threw P0300 was with the car in park, and someone reving the engine just to see how loud it was. But your dealer is right, could be alot of things...plugs...wires... As for P1416 that's most likely just a bad/clogged passenger side air check valve. Easy to replace yourself (PN 12565503) it's the black round valve between the metal air tube coming off the header that connects to the rubber air hose.

ok so if it clogged how do you clean it or do you have to replace it because i can find one around here so i am trying to clean mine

RobLS1

anybody know how

jyeager

Your blue smoke means oil. Oil will very often cause misfires (not to mention rampant knock retard). If the oil consumption is new and there was no 'mishap' coinciding with it, then I'd suspect your PCV valve.

As for the check valve problem? I've no clue. Take it off and look it over. If cleaning it seems feasible do so. Otherwise buy new.
