Sputtering since tuneup Sign In

I have a 2001 Yukon with over 300,00 miles on it. I don't know the engine size, but it's the smaller one. This truck has been awesome. I took it Friday to get a new tire rod, tuneup and oil change. They also cleaned the fuel line or system and the exhaust as well. I picked the truck up and it was sputtering really bad, I thought that it would shut off. I took it back and the guy said that he rechecked it and there was no problem. He said that the exhaust and fuel line or system was gunky so there could be some residue. He said that I should give it a couple of days to straighten itself out. It's better but it's never done this before and I'm scare to drive it. Is this normal?

I don't think this will just go away and surprised they took it right back or gave it back with this problem right then? It must be setting codes to help and true cleaning up intake if they did could throw dirt at a spark plug and run terribly right away and just needs checking.

Plenty of miles but it should still have codes or a code to help find what is going on where. It's NOT good for it to keep driving that way,

   Have a scan done - Even if the CEL is off. post the codes and someone will advise....
Many auto parts stores will do free scans.

Something like that shouldn't do that. What they told you about driving it should make it go away is bullcrap. When you pick that vehicle up after the completed repairs, it should have been running as designed, not skipping and snorting. If your driving around on a misfire that is allowing raw fuel into the exhaust, it is going to cause catalyst damage, which is very expensive to fix.

Never heard of a shop cleaning the exhaust out. How did they do that? What did they charge for that? If it wasn't running that way when you took it there, something happened during their repairs.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
