She was running fine and swapped out the plugs, during which Indy noticed leak from valve cover gaskets ,that was replaced as well. 50% of plugs had some oil around it, the burn area was clear. Some background on this is that, once every 600 to 700 miles, i will get a check engine and it will fix itself, 1, 3 & 7 misfire.

Now after plugs, head gasket and cleaner looking heads, i have a constant misfire on bank6, P300 and P306.

>>Idles rough. I have the DAS ( Star Diag ) working and need help to eliminate O2 Sensor, MAF or other sensors, before i blame the coil pack.

Need some help on what menu functions to go thru in DAS , other than running the QuickTest, also if there are expected values on certain sensors, i would like to
measure those and post as well.

2003 with 75K Miles.

Appreciate all help in troubleshooting this.
thanks

hi,to check for misfire you can go into actual value and check smooth engine running,if coil 6 faulty swap over to another bank.
or you can go into acutations-t1 coil shutoff(something like that) and you can shut off leads a/b-max value= +5.
make sure that oxygen sensors are plugged into correct bank!
also go into adaptations,reset mixture adaptation.

and when you say head gasket do you mean rocker cover?
perform compression test also.

thanks - yes i meant the rocker covers.., head gaskets will be a long job won't it. ,

When you say , swap over to other BANK, can you do this using the DAS ?
If so, what options will get me there from the menu.
