    still getting the P0220…

    Hey everybody, last year I had a lot of trouble getting the reduced engine power message. I think it was the P2135 code. I replaced the throttle body, added a few grounds (neg battery pole to TCM to body to throttle body to engine to PCM), cleaned all thenother grounds on the truck and got the...

    need help from someone with a Tech2 who owns a 2000-2006 Tahoe or Suburban

    Hi, the problem with my truck is that it has the acoustic and exterior lights feedback when locking/unlocking the truck disabled. I cannot activate it in my driver information center. The reason it is disabled: it is a 2003 Tahoe for the European market, therefore (because of our laws) it has...

    what causes my battery to drain

    I was thinking about a new BCM for some time as my truck is a EU version it came with some things deleted in the BCM like the exterior lock feedback (blinker flashing and horn honking when locking the car with the fob) and in order to have these features you’ll need a new standard US BCM. Does...

    what causes my battery to drain

    the lights always turn off when I close the door, I guess that is working fine. Do you know which ground is responsible for the BCM ? Last year I cleaned the two grounds to the frame on the driver side. One on the front left close to the Bumper. And I rewired some grounds in the engine bay...

    what causes my battery to drain

    Battery came new in July 2020 I know…but first time after 3 weeks it was fine, having about 12V left now the second time all of a sudden it‘s only left with 5.5V And the drive inbetween those two times should have charged it back up completely

    what causes my battery to drain

    Battery came new in July 2020. Alternator seems to work fine judging by the charging voltage (14.1V-14.5V). I noticed that maybe 1 out of 20 times the small display in the cluster (the one that usually shows the mileage, Driver 1 or Driver 2, or any other message like „Check Engine Oil“) stays...

    what causes my battery to drain

    Hey everyone! My truck has been sitting for 3 weeks and when I first got back into the truck I checked the voltage, it showed 11.8V-12.2V and the truck started up perfectly. Then I took the truck on a 120km trip. It then sat for another 3 weeks and when I tried to open it with the key fob -...

    03 Tahoe wet interior

    Thanks for all the answers so far! - the weather strips around the doors look ok - I don‘t have a GPS antenna, so this won‘t be leaking - interior is not soaked in water, it‘s „just moist“ - I park on the street, sometimes under trees, so I do have some leaves falling on my car, especially in...

    lower steering shaft worn out ?

    Parts arrived on Wednesday and I installed them on Thursday. Unfortunately I only noticed with the lower steering shaft removed, that the play was not coming from the shaft but from the pinion (?) that it attaches to at the steering gearbox… Is there a bearing that can go bad or is there a...

    03 Tahoe wet interior

    So after my Tahoe has been sitting for 5 days I noticed that the interior was a little wet (dashboard, door panels, seats, etc.), as a result of the moisture the headliner is starting to come down. It has been raining on 2 of these 5 days, but just a little bit, temps were between 40-50...

    lower steering shaft worn out ?

    thanks guys! I'll go ahead and order the shaft, might as well order some other parts too since that saves some money for shipping. PS: I really love my Tahoe but owning one overseas can hurt sometimes :yaoface2: (I have parts worth 230$ in my cart at Rockauto...but adding shipping to...

    lower steering shaft worn out ?

    Hello, I am wondering if anyone has had to replace the lower steering shaft on a 03 Tahoe. I feel like the joints are worn out...when I grab the lower steering shaft I feel looseness towards the lower part of the shaft, where it connects to the steering gearbox. I have already replaced the...

    Solution to Reduced Engine Power Message and p1516. Look Here

    I just realised I could make the engine go into limp mode and throwing all the codes by wiggling the small ground wire on the passenger side of the engine, turns out the wire was replaced already but the connection was made very poorly so it made the engine go into limp mode whenever I hit a...

    intake manifold noise

    I have tried to find the leak with starter spray, couldn‘t find it, sprayed at where the intake manifold gasket is, PCV valve, Purge solenoid, all the hoses, couldn‘t find any leak. I then tried to locate the sound again and it seems to be right around the purge solenoid and throttle body area...

    intake manifold noise

    Fuel consumption increases by about 20% when driving with LPG, that‘s because LPG has a lower energy density than gasoline. The system is plug&play, it has it‘s own computer that reads all the engine data via OBD, the system turns itself on when the correct temperature is reached and turns...

    intake manifold noise

    Hello everybody, the last couple of weeks I noticed that I have a strange whistle sound coming from my engine, my first guess was the serpentine belt, but replacing the main belt didn't help, I took off the main belt and the AC compressor belt and let the engine run for a few seconds to be...
