Powerless
Hell All,
I Have a '93 Blazer 4x4.
Problem 1: When i start it up cold it starts up fine 95% of the time. When it gets warm 95% of the time i have to hold down the throttle to get it to start.
*Problem 2*: When i floor it it kinda goes in the begining but probly at 3 grand it just stop going but the more keeps going. It doesn't sound like it slips in to netural and just fire right up there it sounds like its trying to go.
Problem 3: it smells like its running rich.
I have done a tune up. New plugs, wires, cap, rotor and air filter. None of it seems to have helped anything.

Pull the vac line off of the fuel pressure regulator and see if there is gas inside. A fuel pressure regulator leaking to vac would cause your problem. Also a bad map sensor could do some of those things.
