Hump on floor in back of passenger seat in 2004 savana? by ffrrggyy

I have a 2004 Savana. What is the "hump" behind the passenger seat?
 
I bought this vehicle new and believe I used to just slide bags in behind the drivers seat. I also used to have passengers on the bench behind the front passenger seat who could put their feet flat on the floor. Last summer when trying to slide something in I noticed an elevation on the floor behind the passenger seat. It seems to have gotten higher. I took it to the dealer I bought it at (no longer in business) and to a Goodyear place when getting tires. Both acknowledged the bump and claim they have never seen something like that before. From underneath they say it is above the catalytic converter but there is no bump up that they can see from there.
 
Yesterday I took it to a different dealer for an oil change as an excuse to see what their service would be like. They tell me it belongs there. Then how come I didn't notice it when I got it? Do all of them really have this hump and I was completely oblivious to it until recently or am I just being blown off?

drddinky,
 
About those stop lights: I had to replace the left socket due to a bad ground. This is a manufacturing defect that the NJ state DMV asked GM to issue a recall on. GM refused. The inspection employes all know about rake light problems in these vans for certain years. Mine's an '01.
 
Water gets into the socket and corrodes the connection for the ground or other contacts. There is electrical tape wrapped around the six sockets on the rear of the truck. It was a make-do fix for a known problem. Again, tape was only on wires where they enter the socket.
 
Three long waits through the inspection lines to find and fix this problem. Kudos to GM for ignoring a real headache for GM express owners!

You dont change any sensors until the go bad, when they do the check eng light will come on and will have a code set. As fare as the brakes are concerned, sounds to me like the rotors or drums are warped creating pulstation felt in the steering wheel. Have the rotors and or drums machined when you do the brake service.

I also like the way the seats detach but hate the rattle. I am thinking of coating the bottom the the seat brackets that fit in the hole with some of that tool coating.
 
I have a 2007 chevy express witht the 6.0 and carefully monitor the milage so far (28,000 Miles) I am getting 14-14.5 MPG on the open road and 12-13 in the city. I would be interested what others are getting and if the Milage goes up as the engine braks in.

Engine Problem with 2001 Express by mathusalum

I have a 2001 Express with a 5.0 engine. It started missing and has a slight "clicking" noise. Took it to a shop, they said it needed two injectors. Purchased two, then they said it needed all eight. Purchased them. After $ 855.00 it does the same thing and the mechanics now say that a cyclinder is "washed out". I think I got ripped. Anyway, is it possible that the ecu can be causing the problem? Had a complete tune up to no avail. It doesn't knock, doesn't burn oil, does not smoke, but just appears to miss on one or two of the cyclinders. The miss is constant and consistant. Any suggestions?
 
Thanks!

Have you had the vehicle hooked up to a diagnostic machine at a shop to see if any engine trouble codes appear? you can also buy the diagnostic units cheaply and check for yourself to see any engine trouble codes.
