SOURCE: O2 sensor problem
I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.

If you have a bad booster you would have a really hard pedal and it would take two feet to stop. Sounds more like a fluid leak or a bad master cylinder. Are you adding fluid or do you have a red brake light on?

Check your owners manual .There is a saftey catch that will need to be realased by using your bottle jack and tire stops that come with your truck. If you dont have a owners manual. What you can try is taking a floor jack and a socket place it under the spairtire right in the center where the cable holds the tire in place. start jacking it up until the socket hits the square part in the center once the socket is aligned with the square part continue to jack up it should release it . Its a stupid system but it will work if the cable wont allow the tire to drop .I drive a tow truck and this has happened to me several times with people who have this type of system on a GM.
