Question about 2003 Nissan Pathfinder

2 Answers

Sluggish on the acceleration

When I accelerate the engine goes up to about 4000 RPMs but does not speed up like it should at that RPM level. I have tried different things like taking the OD off...but that really makes no difference. It is acting like it is not firing on all cylinders. Or maybe a plug or two is bad? Any help would be great.

Specs
2003 Nissan Pathfinder SE
77000 miles
2nd owner
Last oil change was 4 months ago

thanks,
Jeremy

    I've had a very similar problem that has occurred a couple of times but then it goes away. Operation may start normal and after taking off from a stop/light, acceleration feels sluggish. Revs up but does not move at comparable speed as under normal operation. After second or third time the dealer identified as a mis-fired piston(?) and changed it but it has done it again one or twice since and now they find nothing wrong. Interestingly enough, I've come to find that when it happens, pulling over and re-starting the truck "resets" whatever the condition is and it goes back to normal but obviously this is not the long-term solution I'm interested in so a logical solution would be much appreciated!!

I have had same problem I took off the gas cap and then put it back on and it seemed to fix the problem.

I recently experienced the same scenario. No matter how much gas I gave it, I could not get the speed past 70 mph and engine was at 4000 rpms. At the first opportunity we stopped about 30 miles later, no gas stations on the highway. Oil was ok, added fuel injector cleaner, and filled the tank. Almost immediately we were at 70 mph and the 3000 rpms.

Our Pathfinder has 110k miles and the original owner. In the past noticed similar experiences going up hills.

Where do you live? We’re in CA. Wondering if a recall is in sight!

    I have a 2003 Pathfinder 4x4 SE. I drove it to church this morning and it was normal. I left church 3 hours later and notice that when I was going up a highway ramp the acceleration felt bogged down. I pushed the accelerator to the floor board and the RPMs flew up from 3000 to 5000 but it had no effect on the forward momentum of the car. It was as if I were in neutral. I pulled over, put the car in park, back into drive and I noticed that the engine was idling at 600rpm. It normally idles between 800 to 1000 (depending on outside temp). There wasn't any fluids leaking out from under the car, no check engine light, so I limped it home. I'm at a loss as to what to do.

Will not excelerate past 4000 rpm


IF you have a carby then take it apart and clean it out as all the throats are not working properly including the accelerator pump.

I have a 2002 Celica GT 5-Speed and I shift at about 4k RPMs when getting on the highway and I still feel I'm accelerating to slow. Am i doing something wrong?


Not driving a corvette? Just kidding. More details are important. How slow is your acceleration? Is it 0-60 in 8 seconds, or 20 seconds? What is redline on your car? If redline is 5K then 4000 is a good responsible shift point. If redline is 8K then shifting at 4000 is probably robbing your engine of it's torque and horsepower band. I believe the GTS model has an 8K RPM redline, the GT may be lower, but in that case, shifting at 4K is too soon for strong acceleration. Your Tachometer should have redline clearly marked. For responsible use, stay below that, maybe 10-20%. For economy stay further still, but for power you need to let the engine use it's RPMS, especially smaller and fewer cylinder engines usually don't make their power until they are half way through the RPM range and above.

Sluggish acceleration. High RPM, High Oil Pressure


I hope I'm wrong but I think your torque converter is failing. Sorry, Gary

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.
