Sounds like you didn't stab the distributor right. I would start there... it's free.

 

tryed stabbing again its dead on fireing order good, today i replaced all vaccum lines, intake,injectors and rail fpr,new pcv, still runs on four cyl, checked plugs again 4 where black and 4 clean , they where rich burning no other contaminates,could the module and coil be going?

 

with all those codes , plus the code 98 ( hard fault present )
you have a short or a ground issue.

 

Salt and Pepper connections,

 

ok short or ground will check and reply thank you for the tips really thankfull.

 

did you check fuel pressure just at idle? plug out when you checked timing?
