 | truck misses when cold?? hay everyone I have got a proble with my 96 350. when i start it up and the motor is cold it almost sounds like it is missing and breaking up. Ill go down the road and there is almost a bucking situation in it. I thought bad gas but no matter where I get gas this seems to happen. It is also only when the motor is cold. not only when it is cold uptside just upon the first start up. It bucks or misses or has a lack of power when you really get on it within the first min or two. I really would think that it would throw a code but i can get one out of it. Any ideas. I have new plugs, wires, head gaskets too. I had a problem similar to this when i had my bad head gasket also. I am lost?? |

| You need a good scan tool which gives actual readings, not just codes! in the long run the cost of the reading may be cheaper then throwing parts at it. Also have you tried the original set up to eliminate the posability it's the superchip? |
