    2007 Tahoe/Issues - engine light

    It was at a GM dealer (different one)...sellers had it serviced before they sold (have the invoice), but from what I've read on this forum, those fancy plugs can foul before their time. We suspected it was that- so glad it was just that!

    2007 Tahoe/Issues - engine light

    So update...hubby takes all his GM work vehicles to local dealer and managed to get my Tahoe scanned on the cheap. Was a cracked sparkplug (outer porcelain) and corroded wire. That's. All. And they did an inspection and washed it to boot :) Sparkplugs only had about 10k on them (iridium)...

    Tech 2 "stand alone" for diagnostic?

    That is probably the deal with the mechanic. Thanks for the info. That's what I was kinda thinking...apples to oranges

    Tech 2 "stand alone" for diagnostic?

    That link brings up a page with a bunch of items. Can you specify which one is the correct item? Ty!

    Tech 2 "stand alone" for diagnostic?

    Thanks for the info! So sounds like even if the mechanic was to buy a "real" one, it's not gonna break the bank. I think he has other financial issues going on, so maybe HE can't afford it. I'll do my research and see if the hubby wants to invest. If he doesn't, we were going to just take it to...

    Tech 2 "stand alone" for diagnostic?

    Reading through all of the the posts I can find about Tech 2 (many people from this forum have suggested buying a Tech 2 to help find potential cause(s) of random Tahoe misfires, dreaded stabilitrak/intermittent CE light etc - won't bore you with issues), but need clarification if anything else...

    Will GM dealers enter repairs in carfax??

    So "checked computer" wouldn't be listed on this report, too? Such a mess trying to track down history. Seems like the newer vehicles are much more of a risk to buy without complete history than older ones. Yeah I know, I know the newer ones have better performance and better gas mileage yada...

    Will GM dealers enter repairs in carfax??

    Woohoo, thanks! At least I can confirm regular maintenance thru 2014, but sadly no info shown about replacements/preventative fixes for those reported known issues. I suspect that during the 2014-2021 period before we bought it (only another 20000 miles) if pattern holds, probably started taking...

    Will GM dealers enter repairs in carfax??

    His mechanic friend at work has the higher end Tech readers and nothing popped besides P0300. Husband also borrowed a midline one that still just shows the P0300. The problem is knowing how to use them properly. I think that we will try to buy a new or used one if this continues or for future...

    Will GM dealers enter repairs in carfax??

    Thanks for the info...too bad they don't enter more. What is Carfax good for then? Accident reports to DMV or local authorities?

    Will GM dealers enter repairs in carfax??

    That's what I suspected and was afraid of...but it is worth a shot. I believe he bought it new and was original owner so maybe some of the problems with that year may have been fixed under warranty? Just grasping at straws at this point. Money fixing it (on the CORRECT issue) is not the issue...

    Will GM dealers enter repairs in carfax??

    That's the thing... I called probably 5 or 6 of them in the greater area near where the owner lived and none of them had records. Daughter said he was meticulous about taking it in and getting the oil changes and maintenance at the dealer. And the vehicle on the inside and outside looks...

    Plugs dirty after 800 miles

    Following 'cause we are dealing with VERY similar crap with our 2007 Tahoe. Also do short drives that barely warm anything up. We are just starting down this rabbit hole, so will share what we findas we go. Already had vacuum test and fuel trim readings done... plugs the next project because our...

    Will GM dealers enter repairs in carfax??

    Husband and I are still chasing the elusive misfire, rough idle, P0300 & CEL (and now intermittent stabilitrac service light) on my 2007 Tahoe. He's going to either do some more troubleshooting himself (or his mechanic friend) to continue to try to chase it down. We have a list of potential...

    2007 Tahoe/Issues - engine light

    So troubleshooting showed no vacuum leaks or other obvious causes or major issues. He cleared the CE light and said to drive it for a few days and rescan. We are probably going to go ahead and change spark plugs and wires as a pretty inexpensive troubleshooting. Hope we aren't going to spend...

    2007 Tahoe/Issues - engine light

    Hmmm, we didn't have the instructions for the scanner we borrowed, so not sure how to find. Hopefully his buddy can narrow down.

    2007 Tahoe/Issues - engine light

    Brand new plugs n wires at its 85k service (sellers did a very thorough service, probably more than required, before we bought-$2300 at a dealer). It's at about 92k and I don't run it hard.

    2007 Tahoe/Issues - engine light

    That is the worse case scenario, of course, but his buddy wants to do a vacuum test first. And it doesn't have any codes specifying any cylinder. From what I understand, random misfires are actually kinda hard to track down...

    2007 Tahoe/Issues - engine light

    Reading multiple P0300. Says random misfire... sigh...his mechanic friend says sounds like possible cam shaft??? (Based on the fact that the misfire seems to subside on higher RPMs)

    2007 Tahoe/Issues - engine light

    Thanks! Husband is borrowing one from his boss. Going to come check it out and if nothing major, going to switch vehicles and he will limp it home. I'm a Newbie with the "newer" Tahoes (owned 4 older Suburbans in past that didn't have any bells and whistles and they weren't fussy at all!)...

    2007 Tahoe/Issues - engine light

    Background- My 2007 Tahoe has been running fine since I purchased about 10 months ago (at about 96k now)- hubby is keeping up on oil changes and he said not losing any and looks very clean (also had AFM "removed" via PCM), and still very low mileage daily driver with a few day trips. No towing...

    Finally Jumped on the Oil Catch Can Bandwagon

    I am the ounce of prevention person, my husband the if it ain't broke bloke. Seeing eye to eye on stuff like this is a bit challenging haha. We balance each other out when I get too concerned about what ifs and he needs prodding with procrastination. I found a few videos with a million views...

    Finally Jumped on the Oil Catch Can Bandwagon

    This is the part that I have a hard time understanding...do all engines have this oil vapor/mist build-up? If that is the case, then should all vehicles have this can? Or is this buildup specific to this particular engine setup because of the faulty cover/AFM system? I'm sure this has been...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I'm sure the material isn't too much I was just wondering what kind of craftsmanship it would take to do that and would be better to have that done professionally if I was to replace it

    Finally Jumped on the Oil Catch Can Bandwagon

    And if the oil looks clean (to the eye at least) how do I know if the catch can would "catch" anything detrimental? That is the tough part...doing preventive "just in case" projects is more my style, not the hubby's....
