I'm getting intermittent codes for misfires on cylinders 1 through 4 and also a random misfire code according to my Flashpro datalogs. I have replaced the plugs and still getting the same issue. I'm not very good at looking at datalogs so I'm hoping someone can take a look and perhaps show me if there's anything else going on. Sometimes it'll misfire in 2nd and sometimes it won't. Car otherwise drives fine, doesn't have a CEL or anything like that UNTIL it misfires. And when it does, the CEL flashes perhaps 7-10 times and goes away.

Some info: Ptuning kit, 4bar map, 4 port solenoid, boost by gear, 91 octane tuned on Flashpro.

I have replaced the plugs with new bkr8eix and re-gapped as well. I figure it might be failing coilpacks.. but all 4? I dunno.

 

Crap fuel maybe

 

 

tight exhaust valves. mine were all tight, had cold start misfiring codes shooting up all over, no codes after valve adj.
might be worth a check

 

what boost level and whats your gap?
