Why could my truck be smoking while going up hill (ONLY UP HILL)?

I have a 1991 ford f250 with a 5.8 engine. I first noticed the issue while driving to work on their highway. I was going up a hill at about 65 mph at bottom of hill by then time I reached them top of their hill I was only going about 55 mph and could feel that they truck had a power loss. I also noticed that I was blowing a light grey smoke from my exhaust that had covered them highway. The only time the truck smokes is while going up hill. I changed their plugs wires and cap and button along with a few bad vacuum hoses I found that were bad. Trying to find out if anyone else has experienced a similar situation and if they figured out what was causing it.

I want to learn to drive better?

Ok so I'm learning to drive rite now I don't have a license and I'm an adult already and I want to start learning to drive before it's too late for me. I have gotten trucks I got my dad's work truck it was a ford f-350 and I drove kinda sloppy because that truck has a loose steering wheel and it is way to big for me and I drove our other truck it was a 2002 GMC Sierra and I drove it really good in the country but as soon as I went to the public roads I was getting a little nervous and every time I act like if I know what I'm doing I drive good and when I think I'm gonna crash I drive bad can ya suggest what I can do or if I should get a car to Lear or a small SUV because I want to learn to drive and not depend on other people.

04 Ford F-250 won't turn over?

2004 Ford F-250 6.0L Powerstroke won't turn over. Turned the truck on and the dashboard lights were flicking. Instead of turning over, the truck's ticking. Both batteries and alternator are testing good. Truck starts fine when jumped. Any ideas?

How much is a spare car key and house key?

I lost my set of keys for my dad's cars and house somewhere in the house. I'm usually a slob and I'm unorganized and that is obviously how this happened. But I've cleaned my room more meticulously than it has ever been cleaned before in the past two days and the keys have not turned up, so I need to make spares. First off, can I do this if I'm under 18? Second, where can I do this? Hardware store? Home Depot? I need keys for a 1997 Honda Accord and a 1999 Ford F350, and also a regular house key. How much will it cost? I have the spares to be copied.

Problem with my 89' F250?

I have a 1989 ford f250 with a 7.5L 460 in it and everytime i start it when its warm it makes a weird humming noise under the drivers seat and it goes away when i press the gas pedal. Also, when i start it when its warm it sometimes will not start until the second time or it will start but it will have lots of trouble and then start with the humming noise. What's my problem?

How long will a 7.3L powerstroke last?

I have a 2002 Ford F-250 with the 7.3L powerstroke diesel engine. It had a banks powerpack system installed with turbocharger, techni-cooler intercooler system, monster exhaust, a pyrometer, waste gate actuator, trans command, and a high boost compressor wheel in 2006. It has a K&N air filter instead of a Banks RAM-AIR, don't ask why. (RAM-AIR is 100x better). I occasionally tow a 38ft. Montana fifth wheel behind it. It currently has 161,000 miles. How many more will it last?
