Hi All,Today on a road trip, my Jeep, 93' Grand Cherokee Laredo, 6 cyl. auto, beganto accept no throttle without slogging down and nearly dying. After limpingalong the side of the highway for a quarter mile, it suddenly seemed toclear and work well for 20 more miles. Then the same thing over again.When it happens, I can press the throttle slightly and get increasing revs,coasting in neutral. Press it too much though or put it under load, and itlooses revs. It will not maintain speed.Have you ever had a weed eater that acted like that? Almost like it's tryingto flood out.Now, I did find the vacuum tube from the head cover to the intake manifoldcollapsed. It was fowled. I cleared it and ran the car 40 miles. Thought Ihad the problem fixed but then it happened again, just as bad.Recent repairs made: I had the alternator replaced day before yesterday.That's about it. Ideas? Any questions? This is a hard problem to describe.Thanks all.Denny
