2 completely different problems, I think.
Hello from Dayton, Ohio! This started 2 weeks ago. It's a 1996, 7.3L, with 214k miles, all fluids and filters are relatively fresh. It's been pretty cold outside, I have no problem starting or idling, but after letting it warm up 20 minutes or so, and start driving, for the first 3 to 5 miles, it seems to hesitate, then go back to normal almost in a cycle. It runs ok, then hesitates for 8 or 10 seconds, then is ok for 10 to 30 seconds, then hesitates again. After it gets more warmed up, it quits doing it. I usually drive it pretty slow until it warms up(not over 45mph, and let it take it's time getting there) anyway. I don't see any extra smoke, and no dash warning lights.
The second thing that started this weekend is, after letting it sit for 3 days (friday thru sunday), I noticed antifreeze on the ground, directly under the water pump, but can't find anywhere that is wet. It doesn't leak while running? I topped it off with anti freeze, drove 150 miles, then parked over night, and there was no leaking during the night. Same story tuesday and didn't leak again until wednsday night/thursday morning. Then, it was just a little on the ground, but nothing under the truck wet that I can find. The hoses appear to be in good shape, and I can't understand why it leaks at rest, but not while running. The temp has stayed normal, and the heater works ok.
I appreciate any suggestions you guys can give me. I'd like to get things fixed, before they become a real problem, or maybe I have one and just don't know it yet? Thanks in advance.............P.S. I probably won't get back to my puter until sunday night.
