Hey y'all! I had code P00C7 pop up. I replaced the MAP Sensor. Check Engine light turned off but, Code P00C7 is stored, I'm having a rough idle, and hesitation in acceleration. I just had the throttle body assembly replaced as well. Any help is appreciated! Thanks!

Reset was already done

I'd try to do it again if it were me. Classic symptoms.....not saying it is ...but...several YouTube videos on it. Try simple stuff 1st.

2017 Silverado...what?  1500?  2500?  3500?  4.3, 5.3, 6.2?  6.0 in an HD?  6.6 Duramax in an HD?

 

Are there any other codes besides that one?

The code means an issue between the Baro data and the MAP data , I'd check for an air leak in the intake system, possibly giving false data from the MAF. I believe the ECM pulls baro data from the map sensor.

Shouldn't is the key word. But maybe something wasn't done correctly?

It's possible. The dealer I've been taking it to seems to give me my truck back with a new problem everytime. It's been going to the dealer so I can maintain my warranty. Otherwise I'd do all the repairs myself.

I have most of my engine and transmission service done at my local dealer. If something goes wrong, I'll have someone to blame.
Everything else, I do myself.

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
