Question about 1999 Nissan Pathfinder

Open Question

Hesitation at steady speeds

I just bought a 1999 Nissan Pathfinder 6cy automatic. While accelerating I have noticed a surge right before upshift. Also while holding a steady speed there is a hesitation that causes the car to ****. It stops when accelerating or slowing down but holding steady is the issue. Not really bad at fast speeds (50+) but right around 40-50mph its horrible. The dealership replaced the fuel pump and filter. Plugs and wires. Cap and button. The MAF sensor and the air filter. The check engine light came on yesterday and i took it to the shop where it read a lean fuel to air ratio. Also engine has started to tick when accelerating. Did i just buy a peice or junk or is this an easy fix?

    I've had the same problem recently. When driving, as long as I'm accelerating no problem really noticed; but, as soon as I'm trying to maintain 40-45 or slowing slightly I feel the hesitation. A vibration in the shifting. It's automatic but reminds me of when I was young learning how to drive a manual and not down shifting at the right speed. I was slowing down but the vehicle need to be down shifted and not doing it soon enough caused this same response. I'm taking the vehicle in today....we'll see....

    My '99.5 pathfinder has the identical problem. Its an intemittent problem but will happen several time every day on my daily commute. Problem started slowly and has become progressively worse over the past couple thousand miles. I have not cehck engine light on, and when I took it to the repair shop they were not able to reproduce the problem reliably enough to diagnose it.

    Searching the net indicates several pathfinder owner with similar problems on various post '95 models. One suggestion I have seen in the net that you have not done is to change the ignition mnodule the sits next to the distributor. Cant hurt since youve done everytning else.

remove the front 02sensor and drive the car like that, remove means complety take it apart from exaust, if problem goes away or gets so much better then your catalitic converter at the exaust is restricted and need a new one

SOURCE: Will the MAF sensor cause

Good Evening, if your truck runs fine at idle it would make me wonder about the mass air flow sensor, however when you first start it your idle air control sensor should open up and let your vehicle to idle up to warm idle and then back to normal. So there are a few things to check.

Hello,
When the MAF on most vehicles reach a point of preventing the engine from starting, you can usually just unplug it and the engine will start. If that doesn't work-
You may want to try having the O2 sensor, ( Oxygen sensor ), checked. It works with other components of the emission system and can cause similar symptoms as the MAF, including preventing the engine from starting.

Testimonial: "Other similar issues are the cam position sensor, which is located inside the distributor. It's easier to just replace the distributor."

Gas consumption is ourageous


first and easiest steps, replace air filter and fuel filter.

next step, watch your driving. slow down, and don't always slam the throttle. Accelerate at a decent pace, not turtle but not rabbit! lol

How do i do the drive cycle on a 1997 nissan pathfinder


The following drive cycle can be used as a guide to assist with re-setting monitors when a vehicle specific drive cycle cannot be located. This OBDII drive cycle begins with a cold start (coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another). This condition can be achieved by allowing the vehicle to "sit" overnight, and then by beginning the drive cycle the next day. Most drive cycles will be difficult to follow exactly under normal driving conditions, so the driver should exercise caution, road safety, and courtesy to others.
  1. . Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on.
  2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle.
  3. Hold at a steady speed of 55 mph for three minutes.
  4. Decelerate (coast down) to 20 mph without braking or depressing the clutch.
  5. Accelerate back to 55 to 60 mph at ¾ throttle.
  6. Hold at a steady speed of 55 to 60 mph for five minutes.
  7. Decelerate (coast down) to a stop without braking.

Vibration on the floor underneath gas pedal


I would venture to say your exhaust is hitting your frame, or, you may need new motor mounts. The exhaust is what I would lean toward. If you can imagine your exhaust sitting under your vehicle, and the fact that the vehicle has a little age, the motor mounts probably give a little, causing the motor to move slightly on acceleration and deceleration, thus your exhaust is going to move, and may be vibrating on whatever its touching. Good luck.
