Ok I have been tuning my car for a while, but I cant seem to get over this one problem. When I start the car and run it for a bit, it runs fine; + and - 5 fuel trims, but when it gets a little hot, the fuel trims get pegged at -22.4 untill i start moving. What can cause this?

If you sit at idle for a while do the ltfts return to -20?

Not just his car, but mine too.
We made sure the EGR code was set so it wouldnt cycle while siting too.
