    We tried that and no it doesn't. And I'm now pretty sure it can't be anything to do with spark and one big problem with it is its not constant enough to throw a code just a pending one unless I let it idle for a long time. But u can feel the misfire or at least a rough sound every now and then while at a light and like I said its not constant. We have now replaced the icm coil to 6 and 3 and all plugs only thing would be the word but it doesn't move when I switch them... and some goes for injectors

    p.s. my friend just told me it could be the MAF. whats yalls opinion on that? i figured if it was the maf the misfire would be alot worse.

    You can tap on the Maf, and the engine will sputter if it's bad. I'd check the compression in no.3 against 1 or 5 since their easy to get at. Low compression will show it's head at low rpms..
