Hi, a 298k miles, It due for a timing belt, and I never adjust valve so I do have bunch of P1399 with 302-3-4-5-6
Replace TB and WP done.... I drove around the block with no issue... check and I do see P1399 still there so I order valve cover gaskets for the valve job.
Today, wife and kid take the van for a short trip: it slow down and stop ... lucky for us some gentleman give them a push to the nearby parking lot. I check and the engine start but can not turn ... no CEL but I now see bunch of P0302-304-5 on my OBD2 reader.
I did replace the main relay before ( less than 3 months ago ).
I need to tow it back home to check plugs/coils but they are less than 10k miles on the sets ( NGK of course ).
EGR valve or Idle valve falling off ???
