Hi Everyone! I just came across this website and I like it already.
I have a 1989 4.9 (300cid) F150 with a aprox. 150k on her. She needs some work but runs and drives well.There is a small problem tho, when I 1st start the motor i get swings in in the idle up and downbut after shes runs for a min she settles down. I will do some research here and see if i cant narrow it down to a vacum leak.
Hi and welcome, glad you like this website!
I`m sure you`ll get the answer, lurk and enjoy.
