    My 07 Denali XL 'build'/Check Engine Lights/Questions

    It had not gone away as of when i replaced the oring. I haven't driven it long enough since to test if the oil pressure is the cause or not.

    that makes sense, I've seen conversion kits so assumed the springs were due to no ride control. I def have the light for service suspension(dont see any resistors in that harness at least). I've attached pictures to this post that you wanted to see. It seems to have had front/rear air...

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    I'll be replacing the oil pressure sensor for sure while I've got it apart! Thanks Geotrash! I found that my rear shocks are blown(air shocks), and while I've been exploring in the engine bay found that the front shock electrical? connectors are no longer connected to the front shocks (up at...

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    Oh ok, well there goes that idea! Its at about 20psi idling in park when hot (about 600 rpms). I'd rather get a tuner, as I will probably dabble with some mods on it after I get everything fixed (longtubes, cam, exhaust most likely). Yessir, more aggressive camshafts pull less vacuum so they...

    any chance that you know what hot idle in gear should be for this motor? I've read multiple different numbers. 550rpm seems low to me(verified with tech 2), but I'm also used to older engines (carb). Thanks!

    ok thank you, I will check that then next! Much preferred to crawling on the ground for 6 hours haha.

    Not sure how to check that, but its a 2007 yukon xl 6.2. So I dont believe it was. Should I change the sensor anyways or nah? I have not had the intake manifold off. Is VLOM dod/afm related? I don't believe I have any of that stuff, or would I still have it? I had to google VLOM to be honest...

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    got the oil pickup tube oring changed. inspected inside the pan, nothing of note just some sludge etc. it seems to have improved driving pressure at temp, and slightly improved idle oil pressure. instead of 8-10 psi when hot in gear and idling, its at about 14-15psi hot/in gear/idling (about 550...

    well, no difference in idle oil pressure. once hot its still around 10 ish. higher oil pressure when driving though! actually stalled when I pulled into the driveway, then didnt want to start (took 3 trys to get it to start again).

    Thank you, that is the gas cap I got. So, something else is wrong with my evap stuff. Thank you for the part # on the oring, I've searched a few times and found multiple part #s.

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    I thought the same thing, as when the oil pressure at idle drops down to like 10 ish psi (depends on rpm), it starts idling rough before dying. I read this post today, after I had the truck setup to change the oil, which I'm doing in the AM. Still planning on doing the oil pickup tube o ring...

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    Replaced my gas cap with a new AC Delco one for the P0455 code (and because sometimes it spun instead of clicking when tightening). Code went away for a bit, but then I got a 'tighten gas cap' message, then a p0455 gross leak/no flow message. It didn't say the gross leak/no flow message before I...

    Getting ready to order parts. Cam position sensor, 02 sensors. Can i use a parts store or do i need to order gm parts? If so any suggestions on where to get them? Also new gas cap. For the oil pickup tube oring, where can i get that and what other parts/gaskets do i need besides it to get it...

    What should I be idling at Rpm wise stopped and in drive? I'm seeing roughly 540 rpm, seems low to me? cruising down the road at 1000rpm its at 22 ish psi (havent hooked scanner up when driving to get exact numbers).

    ok thank you. No reason to change the pump while in there? How long do they normally last? Anyone know what these 2 connectors are? 3 photos, 2 connectors at diff angles.

    My 07 Denali XL 'build'/Check Engine Lights/Questions

    I do have an oil pressure gauge, but was unsure what the actual number is. Im at 13 psi at 538 RPM (seems low to me??) with the engine fully up to operating temp etc. I guess I'll try the o-rings in the intake valley first until I have time to do the oil pickup tube o-ring. Or does the intake...

    Thanks! I have a tech 2 scanner so as I figure out how to use it I'll be good in that regard. Not going to do the parts cannon thing lol. All 4 02s seem to be going up/down appropriately based on rpm etc No issue with cats here in FL, I can just gut them if needed.

    Hey all! Located in central florida, just north of Orlando. I just bought a 2007 Yukon XL Denali. 161k miles, AWD/6.2/6spd. This is for my 'rebuild'/repair thread haha. It needs a lot of TLC, but the body is mint(I'm from the north, to ME its mint anyways. Zero rust, has typical paint fade but...

    I was stationed there for about 10 years(between deployments), I enjoyed it for the most part and the area quite a bit.

    Thanks! Yea, that's why I wanted one! I Really liked every Escalade/Denali I've ridden in/drove. Heater hoses, got it. What are Ts? Just ordered the Tech2 today. It has an aftermarket touchscreen pioneer head unit in it.

    ah, I was west of there at Hurlburt Field in Fort Walton Beach FL. Yea, we mostly did night ops crap. The Air Force variants were almost exclusively used for spec ops missions/transport.
