    Non-Hydroboost Power Steering and Brakes Linked?

    It has to be a fluid restriction, it builds enough pressure with brakes free to work okay but the needed pressure to work with the resistance of the brake applied is insufficient. I would look for a collapsed hose, plugged cooler, restricted filter or some debris stuck in the steering box valving.

    No start issues again

    Okay, the shop did not replace all of the components to restore your security system to functionality; it sounds like they attempted to wire a permanent resistor into the ignition to "spoof" the BCM. That is why the yellow wire was disconnected, they didn't "forget to hook it up" because it is...

    2003 Vs 2007

    Since you dropped the body swap idea and I believe you said the check engine light is out I assume the issue with smog is the readiness monitors are not setting. EVAP can be not ready and pass if there are no codes set so that leaves the 02 sensor heater circuit, the EGR and secondary air...

    Mystery noises in engine bay

    I would suggest also changing the A/C idler pulley and tensioner as well, it seems like they all go about the same amount of time.

    HELP!!!

    Your evap code is for "large leak" which means the evap system is seeing no vacuum at all, your leak is definitely related to the evap system which connects after the throttle body; so you may be hearing it from the throttle body but I doubt that is the source. Remove the evap plunger and...

    Front wheel bearing education

    I also have stayed with Timken as my go to brand, I have heard some say that they aren't what they used to be but I buy a LOT of bearings (I own a trucking company) and I haven't noticed any appreciable degradation in quality.

    2005 Tahoe/Fuel filling problem

    Whenever the nozzle kicks off when there is plenty of room for gas it means that the air being displaced by the incoming fuel cannot escape quickly enough, in the old days the air displaced when fueling was simply vented to the atmosphere via a vent on the tank; since the emissions era this...

    Very Strange issue 2005 tahoe

    The A/C fans kick on when the high pressure side of the A/C reaches its maximum designed pressure, if the pressure does not drop quickly enough the system is supposed to cut power to the A/C compressor to save it from locking up and destroying it. It sounds like your high pressure safety...

    Atf in fuel tank to clean injectors.

    ATF is used to lubricate the pumps and injector o-rings on diesel engines, not for cleaning purposes; the low sulfur diesel blends cause the moving parts and soft parts to fail much more frequently than the older diesel blends so adding some drain oil from the engine or ATF restores most of the...

    How hard does this look to repair?

    They want too much on the buy it now, you should also check with Uber & Lyft about trying to use a vehicle with a Salvage Title; in Kalifornia they don't allow anything with a branded title.

    Cluster Gremlins!

    I think your ABS/BRAKE light is a separate issue, when it rains it can wash brake dust onto the sensor and cause it to stop reading temporarily; have the rest of your gremlins stayed away since you tightened the harness and cleaned the grounds?

    GM better come up with something better than their current engine lineups

    I remember when GM redesigned the sbc and came up with the LS, all of the reviewers laughed at the "obsolete pushrod design" that was so inferior to all of the overhead cam offerings from Ford and the foreign manufacturers. Of course that LS engine and all of its iterations has proved to be...

    What should i do about oil leak

    If you are leaking a half gallon of oil every 2 weeks then the entire undercarriage would be totally saturated and leaving multiple puddles underneath the vehicle spanning from the rear main seal all the way back. If you are not seeing a catastrophic mess I think most of your oil consumption...

    Strange electrical issue.

    It sounds like a failing stop light switch to me, or a short in harness that connects to the stop light switch very close to the switch. Both of those are cheap and easy, change the switch and look for rubbed wires on the connector before you plug it back in; if the problem persists then some...

    Use Genuine AC Delco Parts They Say...

    When the manufacturer sources a supplier they give that supplier the OEM specs for the part, China (or whoever) then makes the OEM part but they also use those specs to make a competitive part to sell under a generic brand name; they charge the manufacturer a premium and sell the generic for a...

    Have power won't start

    Not starting means it is cranking but after years of hearing people say "it won't turn over" when they mean "it won't start" I have given up trying to guess the actual symptom; if I had to guess I would guess that he is having an intermittent cranking issue but it starts fine every time it...

    Engine advice

    Sell it as is and cut your losses, I am certain that engine has many great miles left in it but you will never get your money back by paying someone else to fix it unless you drive it. An AFM delete with hard parts is cheap for a diy'er and possibly one head repaired (worse case scenario) and...

    2011 Tahoe White/Blue Smoke on Startup, Dealer Says New Engine

    The report reads like the tech is blaming worn rings for low oil pressure which is not possible, I also don't see where you complained about low oil pressure. The smoke is likely oil getting in the combustion chamber which can occur when one or more oil rings are failing but that is highly...

    What is this Button? - Solved

    Sometimes people lose the heater/ac fan midule and instead of spending 25 bucks for a new one they run a hot wire to high speed fan terminal; if that is it when the switch is off your ac/heater fan won't run.

    Trans Question - Rough shift 1st and 2nd gear

    My son in laws 04 Sierra had the same issue, we changed the 1-2 and 3-4 shift solenoids and the pressure switch (all accessible by dropping the pan) and it shifts like new now; good time to flush out the old fluid and replace the filter. All 3 solenoids were less than a hundred bucks on Amazon...

    05 suburban traction active every time I stop no codes

    Lazy wheel speed sensor on the front, probably due to a loose hub bearing that is close to needing replacement.

    Vacuum Leak Help

    I think that is the evap vacuum line, did you have a check engine light before you patched it?

    Brake bleed issue

    Times 2 on the calipers being reversed, your bleed screws must be on the top of the caliper when it is mounted; if they are on the bottom it is not possible to get the air out of the system. I have a tech 2 but I have found that a normal bleeding procedure with the ABS fuse removed gets all of...

    Need advice on 2005 Yukon

    I have decided that I am keeping mine unless it gets wrecked, there is simply nothing on these vehicles that is not easily and cheaply repaired and my wife loves it more every time she rides in someone else's newer one. 248,000 miles and this Yukon Xl still feels like a new car driving down the...
