Question about 2004 Chevrolet Silverado 1500 Crew Cab
Coming to a stop my car suddenly stalls. No sputter- just shuts off as if I'd turned the key off. Wont stay cranked unless I hold the gas just a little. I get home (about a mile away) Get back in- it does the same. A mile later I turn it off and back on. All of the sudden- 'reduced power' light is on along with Check engine light...of course I'm hardly moving. Few miles later, turn off car, turn it back on after short while- it is fine- except check engine light is still on.
Driving better the next day- I get Advance Auto to get the trouble code.
It says "P1125 Manufacturer control fuel air metering."
Any idea what's going on with my car?
It happened- but acted CRAZIER on a 5 hour trip. Took it to Honda place. They replaced the Throttle body gasket. Worked fine till now. I have the same problem with my chevy 1500 truck. i found that a few things can cause this problem. The throttle contral modual at the gas peddle, the pcm or (ecu), and the throttle body. try having these items tested and maybe you will have the luck i didn't. i need to change out the throttle body.
These trucks have a drive by wire system,we seen a` lot with a broken ground wire on the rear of the drverside cyl head,this is hard to see just feel and give the wire a tug .If the wire is loose or broken the reduced engine power light will come on.

Have the O2 sensor replaced, it's likely mounted on the exhaust manifold. Should run much better. You can likely find the codes by signing up on Autozone.com, enter your vehicle and save it, then look for the codes.
