I got 99 Silverado 1500 with the 5.3. Pretty sure one of the ac manifold hoses are leaking. I can’t tell if it is at the crimp or just the rubber hose. Either way, is this a common problem? It has leaked everything out of the system.
Anybody found a way to add a usb port to a 2008 sierra without changing radio? I have the 6 disc/am/fm/xm radio now with bise option.
Not looking and doing any performance upgrades, just wanting to replace injectors. The truck is completly stock other than doing away with afm before I bought it. I I went ahead and just ordered a set of 2 hole reman injectors.
Looking to replace the injectors in my 2008 Sierra with the 6.0l. I found some that are aupposed to be an upgraded version with 4 holes instead of 2 and are 310cc. I can’t find any information about these. Anybody have any idea if these truely have any upgrades over the original?
I just replaced the plugs a couple months ago but when iI get a chance I will pull the plugs out and take a couple pictures. FYI the afm was already removed when I bought it and it has 224,00 miles on it if that helps any. This is what I pulled from my scan tool but dont fully understand it. Makes me think of injectors but dont want to throw parts at it for nothing. As far as exhaust, I dont see orhear anything there.
I have a 2008 Sierra 1500 with the 6.0l. I keep getting intermittent P1175 and P0300. I have some freeze frame data but I dont fully understand it. Anybody help me out or point me in the right direction. I was leaning towards injectors.
