Was there a good reason to replace all of those parts? You

should start with the simple things first, such as fuel filter.

After you check the fule filter it also helped with my jeep to

check the transmission fluid. it seems to be on of the most

forgotten fluids. If the fluid gets worn out it will feel like its

sliping when put under a load. so good luck.
