Re: Does my Hummer need an air filter?

When I don't change my honnycomb air filter in my hummer, I tap it on the ground opposite of entry and fine dirt drops on the concrete. Enough to scar the cylinders for sure and sand any filaments...

Re: RPM surge? 2003 H2

My trans started slipping. Pulled the pan and found lots of metal powder around the magnet and in my filter. Changed out the fluid with no results. I think my clutch plates are fried!

Re: Hard Start only when warm H2 2003

I think the main problem is that it doesn't hold the pressure. I have measured 45 to 50 psi at idle at the shrader valve. When stopped for a couple of seconds, there is close to zero pressure. If...
