Re: 2001 silverado 5.3 missing when pedal is depressed
Put a pressure gauge on and here are the results.
54 ign on 55-62 is spec according to my tech manual
50 at idle
60 when vacuum line from relief valve is removed.
When you hit the throttle, pressure goes to 55 but engine still almost dies.
I installed a new fuel filter. Made no difference on my readings.
I put new plugs and plug wires on before I did any testing. It was one of those things I've been meaning to do anyway. It idles good now.
I'm thinking maybe bad gas?
