Are you getting a CEL (check engine light)? Sounds like a COP going bad.

 

all cop and plugs r new this is just kind of an update to my last thread

 

Change fuel filter? Could be clogged, then something shifted in the filter and it ran good, then shifted back and clogged again. The crap symptoms fit a clogged fuel filter though. Give it a shot, they're cheap enough.

 

i've changed the spark plugs coil pacs fuel filter hecked the iac egr and maf no difference

 

have you checked your fuel pressure to see if maybe your fuel pump is on its way out ? i know it seems like out in left field but ya never know....

 

thats a good idea man i'm thinking it's that or injectors now because it started to have random like missfires that only last a few secounds when i turn the key on you can clearly hear the pump and it sounds pretty normal to me this little problem is rueining my faith in ford i'm gonna pull all the injectors tommorow get them redone and if that doesn't work i'm gonna give up and just trade my 97 for a 79

 

Test your fuel psi first man, it's much easier than pulling all your injectors. It could sound just fine when priming but still be weak.

 

Could be something as simple as water in the tank. Try some dry gas first just to see.

 

i draied all the old gas before i started using it i've ran bout 2 tanks of premium with injector cleaner but thanx anyways all imput helps
