Well, i bought one. Have a p0442 (small evap leak..cleared, no biggie). But tripped a p0300, mutliple missfire. Haven't had it come back yet (after racing), but the light didn't come on, but it was there when i scanned it. I guess it was a pending code. Anybody else have that with a s/c on? Curious to see if this is common.

it happened to me once -- the light actually flashed and then went away and when i scanned it it said multiple random misfire
