I have a 96 blazer that when cold will surge through 1st and 2nd gear. Once engine warms the problem goes away. Its throwing codes p0300, p0440, p0700pending and p1192pending wich I can't find anything on the p1192 code. I have done a normal tune up, plugs, wires, cap, rotor. That sort of thing but keep getting the codes and having this problem. Any help would be greatly appreciated

Code P1192 is Post-catalyst Fuel Trim System Bank 1
300 is random misfire
440 Evap Emission Control Malfunction
P0700 Transmission Control System Malfunction

my knee jerk reaction is to think it's running lean and change the fuel filter and take a look at the spark plugs

Thanks for that advice but I have already changed the fuel filter when I did the tune up I just forgot to mention it. That was my first thought to but that hasn't worked. I'm leaning more towards maf or o2 sensors. Anybody think thats a good idea or am I goin in the wrong direction here?
