Hey there guys, I’ve had my 95 pathfinder for three or four years now, my dad got it used but it had low mileage, and the motor had just been rebuilt by a local guy in town that rebuilds racecar engines, anyway back when it was cold I managed to blow the water pump out. Well I go to school out of town so I didn’t have time to work on it until this summer, my dad and I replaced the water pump and al the other parts you’re supposed to replace when you do the water pump, and it runs fine, except when you first crank it up, if you don’t give it ample time to warm up, you back it up and then drive forward and you out your foot on the gas, the engine will rev, and it’s like you’re going but you can tell its only partial power, and then all of a sudden the full power will come back, and it will go through this cycle until it first shifts, after that it runs great and shifts smooth. Any ideas what could be wrong with it?
