Engine trouble: Cylinder one

[SDH3]

I did a search and read the other comments from Av1ator, pacey, etc., here's my story. First of all, let me preface this with I really love driving this truck, I usually alternate vehicles to break up the mileage for daily driving. However, I just realized I put 7K miles on the H3 in the past 3 months. OK, I'm 2 1/2 hours from home on a business trip, and the check engine light comes on. Called Onstar for a diagnostic, they said the engine is misfiring, and they told me to reduce speed, no rapid accelaration, and no inclines. Luckily, I was less than 10 miles from a Hummer dealer, and they said bring it on in, and in less than a half hour the tech had a read on it. He said the number one cylinder is bad, and the parts are on order and should have them in 5 days. No more details than that. When I get the repair ticket I'll post exactly what was done. They put me in a Caddy CTS and sent me on my way, that was Friday. This little caddy is fast, but a car just isn't the same. I'm standing by GM on this and believe it will go smooth.
