help please: son w/'97 5.7 Vortek, int. power loss
Have middle son trying to travel from Western WA state to E. WA state over Cascades. He called and has intermittent trouble with his 1997 1/2 ton Silverado. 208K miles; never much engine work done; new auto trans. 5.7 Vortec. Trouble example: running perfectly on freeway, then looses power...push gas pedal to floor, no power at all, BUT, engine never quits. Then recovers, and runs fine for a while, maybe quite a while, then trouble repeats.
Ring any bells? I hate long distance trouble shooting and not being able to be there to help. I just thought some of you might recognize this as some kind of typical problem with typical fixes. Thanks, Dennis |

Thanks, Vegas. Any tips are a start. And tips are usually only given if there is some reasoning behind it.

like u said long distance trouble shooting is tuff, i mean i doubt it, but it could be a start, if those sensors go bad the car usually doesnt start. i mean it can be anything, from a MAF sensor, MAP, BAP, TPS, hell it could be something as simple as a ground.

I have nothing to offer here, except maybe the truck doesn't like being surrounded by Cougar fans?
Woof. *UW* :) Is the truck throwing codes? Check engine light coming on? Swing it by an Autozone and have them scan it for free. That may just shed a tiny bit of light in the direction you need to go. |

Might be a partially clogged fuel filter, or bad gas.
I agree: "Swing it by an Autozone and have them scan it for free. That may just shed a tiny bit of light in the direction you need to go". |

no way to know for sure...but if no check engine light..i'd say a fuel pump

RE: help please: son w/'97 5.7 Vortek, int. power loss
I would also say fuel pump is a likely canidate
|
RE: help please: son w/'97 5.7 Vortek, int. power loss
my truck did something similar to that and it wound up being the fuel injectors.
|
RE: help please: son w/'97 5.7 Vortek, int. power loss
I would say something along the line of the fuel Fuel pump, fuel filter, or fuel injectors.
