    2012 Yukon Denali

    I took it to the dealer and had them look into it, I know they have the ability to check the VLOM. Also, I’ve never had any type of lifter tick or anything. So I’m praying its not a lifter or anything.

    2012 Yukon Denali

    I took the Denali to the dealer today. I drove it all day yesterday and didn’t get a single misfire everything ran great. I started the car this morning and the remote start wouldn’t work, it would try to start it and die. But would start with key no problem. But all the electrical issues...

    I have no idea. As far as I know it’s the original pump.

    2012 Yukon Denali

    When I say “awhile” guess I mean sometimes it’s 20minutes driving around town and the highways, some times it’s an hour or so. It goes away for awhile and doesn’t misfire, then all of a sudden it’s back to misfiring. You can feel it, when it happens at idle you can feel the car shake. Could the...

    2012 Yukon Denali

    Ok, so I’ve swapped everything off #7. Coil, plug, wire, and injector for a brand new one. Drive fine for a while, but after awhile it starts misfiring. I even changed the lifter oil filter. I have no idea what is making this thing misfire. I have no more electrical problems, nothing is flashing...

    2012 Yukon Denali

    I have swapped, coils, spark pugs, plug wires, and am currently swapping injectors from #5 to #7. If that doesn’t make a difference I don’t know what my problem could be.

    2012 Yukon Denali

    I look the battery to Interstate and had it checked. It was reading 12.4v and 715 CCA. It was rated at 720CCA so I don’t think a cell is dead or bad. I cleaned the fuse box connections and I cleaned up all the ground. I wasn’t getting any voltage drop on any of my wiring. I haven’t noticed any...

    I’ve never had a problem starting or anything. Would autozone or O’Reillys be able to text it and tell me if it’s bad?

    2012 Yukon Denali

    I cleaned the positive cables at the battery but not at the fuse box. Im hoping that my misfire isn’t a collapsed lifter. I haven’t heard any noise from the valve train. I plan on getting a new negative cable today($100 for a damn cable?!?) I’ll clean the connections under the fuse box

    2012 Yukon Denali

    So I’ve got a 2012 Yukon Denali AWD with 200k miles. When I bought it, it ran and drove perfect. A couple weeks after I bought it, I decided to change the plugs, clean the MAF sensor, change air filter. Ever since then it will randomly freak out. By freak out I mean the gauges will drop to 0 and...

    Hello Everybody

    Hey Everybody, I just purchased a 2012 Yukon Denali AWD. Love it so far, bought it up in Iowa and I live in north east Kansas. It’s giving me some problems but nothing I didn’t expect for the miles it has. I also own a 2007 Trailblazer SS AWD that I love. Hope to learn lots of information from...
