Problems with lift kit

Also posted in Compact area, hope that's ok.

Hopefully somebody can help.....  I had a 2.5" Fabtech lift kit installed by Anthony's Planet Pickup (S.A., TX).  Ever since the install I've had to put up with the ABS & BRAKE light coming on intermittently.  The truck will "shudder" when the lights come on & occasionally it will stall.  The brakes still function normally, even when the warning lights are on.  Also went from 195/75/15 tires to 31x10.5/15's, could the tire size change be causing the problem?  I didn't get a new speedo gear, could that be causing "cornfusion" with the ABS?  Anybody got an idea on how to fix it?  It's a real pain in the ass, especially when it stalls going down the highway.  I have to turn the key off to restart it... can get exciting in highway traffic!!

Oh yeah, can't say that I'd recommend either Anthony's Planet Pickup OR Fabtech after all the problems with the lift kit itself!

Thanks,

bill
