Intermittent problem, I've tried differant remote starters (as1774 and 1272) differant gmt4 and differant evo all's same problem .  Tried firmware 70.16 and 70.17 problem still there. Everything programs fine and seemed to work but later stops . Any suggestions would be great

Answer 1

I would suggest removing the modules and T-Harness for a day or two...If the problem still exists its a problem in the vehicle itself and not with the modules or t-harness.
