pjb,s e/bay build up

Really Id like to find out if its something other than just needing a tune first before I spent money on a tune.

Trying not to throw anymore money at it since Ive thrown too much already. The main reason for thinking about giving up is that I cant really afford to fix it much more.
Ive had alot of stuff checked out so far. Ive got a book on the EEC-IV system with troubleshooting in it.
