2001 pathfinder slow go uphill

[kegmom3]

My 2001 pathfinder is sluggish when going uphill, just slows way down to35 mph. Once over the hill, drives fine. Any ideas?

If you don't have any MIL codes [check engine light], you could pay for a chassis dyno test to read the real world rear power to the tires/road and compare with whats AVERAGE.

Cheaper would be to find an 2001 magazine test and compare accelerations say zero to 60.

"For 2001, Pathfinder receives a huge bump in power, thanks to Nissan's new VQ35DE 3.5-liter, DOHC 24-valve V6. It packs 250 horsepower and 240 foot-pounds of torque when equipped with the five-speed manual transmission (SE only). If you prefer your shifting done by an electronically controlled four-speed automatic transmission with overdrive (standard on XE and LE, optional on SE), the engine makes 240 horses and 265 foot-pounds of torque. That's a 40-percent increase over the 2000's 170-hp 3.3-liter."

"Nissan says the 2001 4WD model with automatic transmission is better than two full seconds faster from 0-60 mph than last year's truck."

8+ seconds 0-60 is what I found

Thanks for the response, when this began, the truck would vibrate pretty severely for a brief time and then loose speed. Now the vibration rarely happens. The first time was not on a hill but flat stretch. Mechanic suggested fuel pump, but is not sure.

Adding fuel injection cleaner when filling up helps some what. The truck has 212,000 miles and I hate to put a lot of money into her although otherwise she is great. Shiny, pretty, I just love this truck.

You probably owe the truck a great deal in 212k/7 years................I'm amazed the pump lasted this long but highway is less stressful.

I would have expected you to have spent $14,000 on tires, brakes and mainteance repairs by now? Since the average Civic costs $1300 per year.
