What is the gap for a spark plug on a 2004 gmc envoy?

.040 to .044" would be normal. The gap should listed on the emission sticker under the hood. Make sure you use the O.E. AC/Delco plugs. This engine will run on those the best!

The shop says I have water in my air injection jump, no real issues with it running just a service light on. waht should I do 2005 gmc envoy V8

You will need to fix it! Thats one of the key componets to the emissions of the vehical. It's not a hard job you can fix it yourself. It's under the truck on the drivers side bolted to the tranmission crossmember. There are a two or three 13mm headed bolts going up through the crossmember holding the pump in place. Then there are a couple of electrical connectors and two hoses going to it.

2002 gmc envoy xl air bag light is on

You will have to be very careful!!! There have been cases where the airbag lights come on because of an internal computer problem. If you go to your dealer, or maybe a local shop, they will have to hook it up to a computer to determine the problem. Not to get too excited, but some people have had the bag actually deploy, so I usually make that known to anyone I help with an airbag light. Hope all goes well, and please be safe.
