Check the fuel pressure at the shredder valve, you should have 13 to 13.5psi, anything other then that will give you problems in the GM TBI. If the pressure is bad, then you may have to replace the fuel pressure regulator at the bottom of the TB. 
Good luck and keep me posted.

pushing the accelerator to the floor causes it to go into clear flood mode .the control module reduces the fuel injector pulse width in order to increase the air to fuel ratio. It could be get to much fuel , leaking fuel injectors or a bad fuel pressure regulator . Pull the vacuum hose off the regulator an see if fuel drips from it , if it does the diaphram has a hole in it .

I have a 1991 Chevy s10 fuel injected 5spd and at stops the engine does not idle down after decelerating, instead it idles halfway wide open at stops. I would like to know the solution to this if possible,...


It is the gasket underneath the throttle body. It is being sucked in at one corner causing a big air leak which caused the engine to idle at about 2500 rpms. You will probably have to buy a throttle body repair kit which will include a new gasket. This should fix the problem. You didn't mention engine size, but I think the 2.8 v6 is the engine that had this gasket problem.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.
