2000 silverado service engine light

21 posts in this topic

The truck is a 2000 silverado 2500, 6.0l, 130,000 miles. I am getting a service engine light when I am at cruising speed over 55 MPH, It doesn't come on until I am over 55 mph and it goes off as soon as it gets below 50 mph. Takes about 2 minutes of driving over 55 when I first start out, but after that as soon as I reach something over 55 it comes on. If I accelerate fairly hard it goes off til I level off again. No symptoms that I can detect, runs smooth at all speeds, plenty of power and idles fine.

Anyone got any idea of what I am looking at?

The truck is just telling you not to drive over the speed limit grin

I would say it could be anything from a TQ issue to an emissions issue.

I have not seen this/or recall it in the past with other makes. Could be anything.

I would have a code scan done to see what is found.

I kinda figured I was going to have to have it scanned, just thought by chance I could avoid it.

Sorry I am not a Chevy guy, so I was hoping someone else would have your answer, because that was the best one I had whistle . I would pull codes on it and go from there, atleast we would have a direction to go in.

There are literally thousands of possibilities that can turn the check engine light on. The first step is to identify the code and then the fun begins! What happens if you set the cruise at 45 for the same amount of time it takes for the light to come on at 55?

No worries....I have not lost my sense of humor smirk

It stays off as long as I am under 55 MPH. Doesn't matter how far or long I drive it.

I may not be able to have it checked for a bit, but when I get something I will post what I get.

And if I am doing over 55 mph and slow down to under 50 mph it goes off.

I would say if you have no running concerns, you should be fine to wait awhile before having the codes read and a repair made.

Just had it checked and the error is P0300 on cylinder 6, according to what I was told it is a random miss. Before someone suggests plugs and wires, I already tried that last week.

I had it scanned at Auto Value and the guy who scanned it said since I already changed wires it could be a sticky injector. Does that sound valid?

I am running some seafoam through it now, yes I realize that is a long shot but it sounds easier than cleaning or changing an injector.

Well you should have did a cap and rotor along with the plugs and wires.

My truck did this and it was the Cap!

I don't think it has a cap on and rotor on that motor. I can't find any reference to a distributor cap and I pretty sure the coil pack don't use a cap and rotor. But good idea though.

The 6.0 motor does not use a distributor cap. It has individual coils mounted above the valve covers and a short plug wire to each cylinder. Same set up as the 5.3!

Upnorth, Why not swap the #6 coil with an odd number coil (1,3,5,7) to see if the misfire follows the coil?

I will give that a try.

Still there. I am trying to eliminate the easy stuff and I am trying to change the fuel filter and of course the dang lines are stuck good. I have been spraying penetrating oil, tapping the nut and trying to loosen it for a couple hours and getting absolutely nowhere except close to stripping the nut mad

Anyone have a surefire tip to get those things loose?

I remember the days when fuel filter was under the hood away from all that fricken corrosion, what were they thinking to moving back by the tank confused

    • Riiiiight... How come they didn't produce this document 8 years ago...
    • I would have started out at a young age, teaching them right from wrong. And that regardless of their gender tell them that I love them. When you make a mistake, you own up to it and be accountable. You do the crime, you do the time. And I that I still love them.
    • I thought you were AGAINST fake news now?
    • That's a good little tip.  I'll have to give it a try.  
    • I may not be an economist but it doesn't take a genius to realize that accumulating debt at the rate we are now accumulating it is a recipe for disaster. Debt is more than doubling every 8 years. There is no sign that debt accumulation will even slow down in the future and there is definitely no indication that we will start paying it down, unless you believe the Donald when he said he was going to eliminate debt in 8 years before he said he wasn't going to do that any more.   As Purple indicated above if you are OK with saddling your grandchildren with all of the debt that your and my generations accumulated and can sleep well at night then good for you. I think the party of accountability should start holding someone accountable but you and they just want to continue kicking the can down the road. What do you care? You won't live forever, right? Might as well let someone else worry about it.   Are all government policies rooted in fact? Everything that you or the party that you constantly support proposes is able to be defended by facts? What about all the morality laws, nothing based from religion is factual. Are abortion laws based on facts? How do you know if a woman should have ultimate control of their body? What are the facts that support it? How about gay rights laws? What facts do you have that support not allowing gay couples the same rights as heterosexual couples? What are the facts that support it being a bad idea that I buy a car or a 6 pack of beer on Sundays in Minnesota?   There are plenty of laws and Policies that are enacted by all types of politicians that are unable to be defended with facts.
    • Geez...we must fish the same lakes  Both of these posts above have become common now that "ice castling" has become the latest fad and everyone and their mother is on the ice.  There is an abnormally large % of those with the shiny new toy who chose only to save money on their generator, but spend as much as they possibly can on their truck and fish house.  I can spot them from a mile away...3-4 guys get out of the truck, they circle around the fish house a few times wondering how to get it lowered to the ice, then they finally figure it out, and 2 of the guys offload the residential home backup generator and carry it 100 yards away, 150 pulls later they get it fired up, and I only know because it's so loud it rattles the dishes in my cabinets.
