Any ideas anyone? o2 sensors in correct place, new maf, new plugs, check variocam solenoid and bracket...swapped those as well and misfire remains on bank 2... any help??

 

I had same issue did you do passenger side valve solenoid between cylinder 4 and 5 coil packs? Just change the valve with a new one and the bracket. If your positive its not the valve, change all your passenger coil packs.

 

Also are you showing p0304-p0306. If there not showing as a code how do you know they are misfiring I see you wrote only code p0400

 

Dude just put new valve solenoids on both sides and read this thread. Ps sonnen porsche sells them for 160 http://forums.rennlist.com/rennforum...ouncing-7.html

 

what i did, was swap all coilpacks from one side and the solenoid valve w/bracket to other side, just to see if it was gonna move to the other side. Still bank 2 basically shuts down. its doesnt really stay on, but what is strange, is when i disconnect the maf, it at least runs(poorly), but both banks active, replaced maf w/new one, and same thing..if i disconnect it, I can at least get it to engine to stay on.. Keep getting the O2 sensor swapped code. any other suggestions?

 

car was running just fine, just had vacuum leak before, and all I messed with secondary air diverter valves, which all looked to be plumbed properly... turning out to be one of those issues...

 

check your cam sync on the durimetric. Does the misfire go away after 3000 rpm and run like crap under 3000?

 

I dont have a durametric(i know, i know.....) need one asap, but if thats the case and it does clear up after 3k...what does that mean..?

 

just strange that it ran strong, until I got in the secondary air area... Too convenient to just happen right afterwards....and i know there arent any air leaks..

 

How does the car idle?

 

really rough, then it shuts off... right bank will shut itself down almost immediately, only way i can get it actually even stay on is remove the maf (which is brand new), but still very rough idle

 

well it can be a broken timing chain or just the oil ring on the intake cam.

 

i know anything is possible, but all this happened after i worked on the secondary air...the key cycle after is when it started doing it.. if i remove the maf...then both banks are on, just rough...plus i keep getting the p0040 code, o2 sensors swap(although they aren't)...

 

you sure you have the clips on the solenoids right? the valve by the secondary air pump is the same plug as the cam solenoid.

 

are you talking about the variometric solenoids between 4&5, because i originally never took those out... and by clips, im assuming plugs to sensors right? any other ones around that area that i couldve crossed?
