    Replace 4 Ball Joints, 2 Tie Rods and 2 Stabilizer Links

    I would use a BFG and chisel to tab the tabs up. I hate the complete control arms. I bought Moog ones for my wife Envoy Denali and sent them back. I received the same one in two different boxes. I spoke Moog about and confirmed it. I asked what the part number was for ball joint and was told...

    NEED HELP Upper control arm bolts coming loose ?

    If the upper control arms are that bad the rest of front end can't be in great shape. I've rebuilt two of these so it can't be that hard 🤔. I would check the LCA, ball joints and tie rods. They can be pretty bad and the truck drives fine.

    Another fuel injector install aftermath question Yippee!!

    The sensor on the manifold is the MAP sensor and if you don't have a MAF this is one of the ways the truck calculates the fuel trim if I recall correctly. There is no fuel filter external to the tank on a 2005 Trailblazer which I have. Check the fuel pressure mine ran just fine on 38 psig...

    NEED HELP Chasing Gremlins?

    Can I ask a question? Who did the wiring for sub woofer and amp initially? You seem savvy on the electrical area but if someone clipped a wire or connected where they shouldn't it can cause chaos. I haven't learned as I have two blazers with that type of wiring and have had the wires arc.

    SOLVED! Higher LTFT at idle and higher at rpms

    OK this one is solved. It was the fuel pump. I got the new one in and ran the truck thru it's paces. Idle never changed from 650 rpm, the LTFT was negative for the most part but never above 1% and STFT swings were much lower about +/- 8%. I think the intake gaskets were leaking a little bit...

    Fuel pump won't fit thru opening of tank

    Both of his pumps had a smaller diameter reservoir. I am having getting pump past the throat. What I suspect is someone replaced the pump and it wasn't the correct one. Or my old eyes aren't seeing the original sealing ring but I did pull off a green o ring
