I've got 2 problems actually, first my check engine light repeatedly flashes off and on, the manual says it's the e.e.c., we replaced the relay and the fuse and it still comes off and on, a friend told me it might be the computer itself.
Second When I start my truck up and give it gas it'll make a rattling noise, but only for a little while, it stops after about 4 minutes of driving, sometimes it'll last a while though. I don't really know what it could be, any ideas?
