    Picked up a 2006 gmc envoy Xl gas mileage...not so good

    I would repeat what others have said about a plugged cat. Can you give us your coolant temp reading when warm? These trucks are very sensitive to correct coolant temps, and running for even a few months with temps in the 185 to 195 range will plug the cat. Also, if it ever had a bad misfire...

    Differential cover

    This is the one I used instead of the factory plug. $1.99.

    Differential cover

    I bought a hex plug from the local Princess Auto to replace that silly 3/8" square hole plug, and a new factory cover. It came with new bolts and gasket, for about $30. WAY less than an aftermarket cover, plus studies have show that factory covers flow fluid way better than aftermarket ones...

    Video: What are accessories worth in HP?

    Reminds me of a project that we did as competitive pistol shooters many years ago. We took every 1911 accessory available and added up all the claims for recoil reduction. We concluded that, if you installed all this junk, your pistol would recoil downwards and would fly toward the target with...

    Best exhaust system, muffler resonator tailpipe

    True. I guess I should have added "quiet" as well.

    Best exhaust system, muffler resonator tailpipe

    Northeastern Exhaust is made in China. Based on reviews, it seems to be good stainless steel (non-magnetic; unlike the Walker SS) but hangers and gaskets seem to be cobbled on without exact placements, so there may be installation problems. If it was me, I would certainly give it a try. Let us...

    Trailblazer remote/alarm issue

    As far as the key setting off the alarm, this is common. Cool as ice is correct. You can replace the door lock actuator, and this will fix it. It is a fiddly repair, but straightforward.

    Help with intermittent ABS issue

    Most Innova scan tools now have ABS codes. I also use the BlueDriver and like it. We cannot emphasize enough how important it is to get those trouble codes. Wheel speed sensors are a common problem, but the important thing to remember is that the code is NOT the cause; it shows the symptoms...

    Broken outer tie rod end

    You can even get EXACT toe-in using two straight edges and two tape measures. It takes lots of fiddling and adjusting an 1/8th of a turn at a time, but you can duplicate the computer in your driveway. I used aluminum U-channel about 4 feet long from Home Depot, bungee-corded to the wheel near...

    Torque for iOS

    The actual Torque app that everyone is familiar with is from Ian Hawkins. As far as I can tell, all those other apps on the app store are fakes, ripoffs or just trying to cash in on the Torque name. As far as I know, Ian Hawkins has not released an iOS version. (Hope I'm wrong though!)

    Slow crank no start

    Just one more thing to eliminate. Did you check to make sure there is oil in the engine? You said you had a recent oil change. It actually sounds more like the engine is seized.

    Fuel Trim Questions

    Easy to tell if it's been replaced. The factory cord has a round sensor near the male end.

    Fuel Trim Questions

    Can you also let us know the coolant temperature when warm? This can tell us if the thermostat is sticking open. This will definitely affect your long term FT. The other issue with Silverados at those temperatures is the block heater. Are you plugging it in? If so, has the block heater or block...

    What Are The Best Brake Pads? Cheap vs Expensive Tested!

    I agree with you entirely. We pride ourselves on being enthusiasts in this forum. It doesn't mean we don't see the figurative "orange peel." It means we share information to keep our vehicles running good, solve problems and customize the ride, performance, enjoyment and looks. We don't duck the...

    What Are The Best Brake Pads? Cheap vs Expensive Tested!

    In my opinion, there is far more to brake pads than simply how long they last. Fleet pads designed for long service life would be a poor choice for most of us because we also want stopping power and good brake feel. This is where the huge difference is. Better pads provide better stopping power...

    Replacing Pads & Rotors, Front & Rear

    I am going to try the new Raybestos Element 3 pads. With new calipers and rotors, I will be able to compare them back-to-back with the Akebono ProAct pads. The Akebono are fine, and give the OEM feel, but I just find them a little soft for pedal feel. Initial bite is good, which is what I...

    Replacing Pads & Rotors, Front & Rear

    On the Nucap page, click on NRS Brakes or go to They don't have an application for our 360 platform but seem to cover a lot of pickups. I have never tried them so can't make any judgements.

    Replacing Pads & Rotors, Front & Rear

    I find the OEM pads (which Akebono are) to give me a slightly softer pedal than what I like. They are better than the worn pads but I sure liked the Adaptive One for both life and feel. Brake pads actually contribute a lot to the feel of the braking.

    Replacing Pads & Rotors, Front & Rear

    For your application, I would suggest you look at pads with the Nucap Retention System (NRS) backing plate. Some EBC pads use this, as well as the NAPA Adaptive One pad. Also, NRS now makes their own line of proprietary pads. Research the NRS system and you can see why I recommend them. They are...

    Rock Auto idler pulley w/ no bolt.

    Also, most new idler pulleys will not fit the old flat washer. Don't worry about it; most are designed to install without a washer if the old one doesn't fit.

    Thanks for the quick reply. Any particular place on the circuit board I can take a magnifying glass to?

    Lost mileage and gear indicator in instrument panel cluster

    After I replaced two more stepper motors in my cluster - which was strange because both were from the batch of "newer" steppers - the readout for mileage and gear indicator seemed to be a bit lazy afterwards. Every few weeks, it would take 30 seconds before they lit up. Every other gauge was...

    Replacing Pads & Rotors, Front & Rear

    Yes! Thank you. Legally, aircraft need to be able to reach go/no go speed (V1) and then come to a complete stop using no more than the available runway and without the use of thrust reversers. They use multiple rotors (and none of them are slotted or drilled!) They have HUGE brakes. I have seen...

    Replacing Pads & Rotors, Front & Rear

    Yes, the improvement in braking feel and performance is strictly going from old and worn pads and rotors to brand new ones. There is nothing wrong with Brakemotive and nothing wrong with GOOD QUALITY drilled and slotted rotors. Lord knows, we do a lot of things strictly for the look. But that's...

    Check Engine Light: 01 Pontiac Aztek Help

    Rear O2 sensors should read very steady. They are there only to gauge how well the cat convertor is performing. Front O2 sensors should jump very frequently (several times a second) from .1 to .9 volts. Generally, trouble codes don't point at causes; they point at symptoms. Your sensor could...

    Front End Growl

    I know it's simple and you have probably already done this, but there is little clearance between the rotor and the backing plate. Could the backing plate be touching the rotor at any time? It is more of a tinny growl though.

    Front End Growl

    It could also be the right hub, unless the sound is clearly coming from the front left. Strangely enough, on our platform there have been forum members in here who had to change both hubs when they found their first guess was the wrong side. Usually when you turn left and the sound goes away...

    Sudden RPM jump while accelerating

    The other common cause of slow acceleration on the highway is a cat converter starting to get plugged. It bogs down when you try to accelerate until it forces a downshift. If the truck is new to you, it might have had a history of misfires or a low coolant temp sensor or bad thermostat. These...

    Add tranny fluid?

    Due to the design of the transmission pan, plus the nature of the fluid, it is vitally important to check the fluid when it is hot, in park and the vehicle level. The system is sealed, so it should not lose or consume fluid normally. This is why we like to check it after driving, with the...
