Removing air suspension, replacing with coils

To get rid of service message take it to HUMMER to have them reprogram the ecm

Actually, it does not. Maybe I got lucky, but after a program, revert to OEM, and program I no longer receive the air suspension message. It's been at least a month.

Note I've also run the battery dead for two days, yet no error message.

Can anyone tell me if it rides better or worse with the coils??? I have an 03' with a "service air suspension" and the garage says he thinks its the sensor but no way to tell for sure. A new sensor is 500 bucks and I can get the whole coil set up for that, but I'm worried it will ride really stiff. Any feed back would be greatly appreciated! I also need a new exhaust for it but can't seem to find a stock exhaust for a hummer. It has a flow master now and its pretty pricey to replace.

I noticed very little difference, if any, after switching to coils.

Thanks egan... Seems better long term to change them to coils.. If I don't next will be the bags or compressor..

While the coils may not offer a better "ride", they do offer less maintenance of the rear suspension system overall. To stay with the air bags and compressor means to have to guard against eventual air bag leaks, sensor malfunctions, and compressor burnout.

For the cost of the springs to be purchased and installed, seems to me you'd be much better off with the coils and not the older air system......just my .02.
