I have a 1995 Suburban 6.5td 1500 that has just started ascting up on me. When it gets hot (after about 10miles of driving) the idle sometimes jumps up to about 1000 rpm from the normal 700 rpm. It also will also either not lock the torque converter or will lock and unlock when it feels like it. If it is cold out it genrally does not do this. It seems to go away after 5-10 minutes of acting up. I pulled the codes last night and only got 12 repeating indefinately. Any suggestions?
