To who it concerns or can help, I had to replace a head on my 1991 Ford Ranger 4x4 ( 2.9 L.) after the soft plugs fell out. The motor was not showing hot but it still broke the head. My question is why does it start up fine and runs until it warms up and then dies and will not re-start until it is cold? I did every thing according to my Haines Manual but am not having any luck. I am not a novice mechanic I was
1000 hr certified in 1971 and have kept up on new systems since. I am at my wits end. Please help. Sincerely, Samuel Springer
