Alright guys here is the deal i just had to do a fix on my expedition i had to pull the valve cover off the passenger side and clean the up the cams and followers etc etc well everything went smooth got everything back together went to start it up it fired up then died immediately tried it again fired it up it again died immediately once more i fired it up and gave it some gas it was rough to say the least the rpms were really jumpy my guess is a vacuum leak somewhere but i also noticed were i had to disconnect some coolant hoses that ran from down the side by the trans tube they have came apart and i pushed a lot of coolant out could them hoses be the problem or something other than a vaccuum leak any advice would be great (97 expedition 5.4l 4x4)
