Hi I have a 96 blazer that surges from a takeoff. It only does this while the engine is warming up. Once the engine is warm the problem seems to go away. It seems to only do it through 1st and 2nd gear also. I have changed the maf sensor, the plugs, wires, cap, rotor, fuel filter, and coil. None of these things have made any differance in the way it runs. Could this problem be o2 sensors or the ignition control module or even possibly the egr valve? It throws codes like p0300, p0440, p0758, p0700 pending, and p1192 pending. I am at a loss so any advice would be appreciated. I erased all the codes before I put the new parts on and now I don't get the p0758, or the p0440. What should I do?
have the same problem?
