Nissan Sunny B15 Acceleration problem

Recommended Posts

I own a Nissan Sunny 2003 JDM Model (B15).

 

I'm not a car geek, so I'm afraid I may not be able to explain the issue well.

 

I'm recently having some sluggish Acceleration issue with the car.

For example one morning I wasn't getting any speed on the acceleration.

Looks like it's moving with the speed of lifting the break.

I shut it down and went home. After few hours I came back and started it.

All of a sudden it came back normal with a very fast acceleration.

 

Is that a Known issue with the car?

Have anyone experience this before?

If so, what might be some probable solution?

I'd be really helped.

 

Thank You

While experiencing the hesitation, have you also experience any excessive smoke especially white smoke? When this happened car was overheating? Have you check the coolant level and color is fine? What I am suspecting is that car must have overheated while driving without coolant or less coolant and that resulted in sudden power loss. However once car engine overheat and head gasket leaks, it causes massive power loss, but on the contrary if head gasket leaks then it can never be fine again unless you open the engine head and change that damaged gasket. May be more experience technical guys can shed some more light.

No smoke at all.

No overheat as well. The engine condition seems really good.

The temperature gauge was fine as well.

The car's condition is pretty well in comparison to the mileage.

 

Thanks a lot for your opinion.

If it's just one of incident, I wouldn't bother much but just remove, check, clean and install all spark plug once to eliminate any doubt for foul plug or loose HT leads (if any).

For sure loose spark plug wire must have caused this, whenever happen again just tap on wires and see if it correct the issue then you need the new spark plug wires....

@Aumio as per my experience I had similar issue of my LR Discovery loosing power when operating at optimum operating temperature. However switch it off for 30 minutes and start it up with cooler engine and it used to be fine. This problem also occurred when my petrol tank was half or less than half. The solution as it turned out was simple, the fuel pump for my Disco had gone bad. Try checking the fuel pump, that might solve your problem.

      With @Barry raising the topic on Turbo installation on his favorite truck, he has got me thinking of getting a Turbo installed in my Nissan Pathfinder 2001 model R50. Recently I have been watching a video breaking the myth of cheap turbo sets found on ebay installed on a vehicle in like 10 minutes and is like a fan only which is added to the intake. This turbo set claims increase of 50 hp on the said vehicle, but does nothing except made a sweet sound. As these guys explained that the turbo or super charge is all about getting compressed air into the engine. I now am more curious to learn about turbo charging a vehicle, in particular my Pathy R50. I used to have a 1991 Mitsubishi Eclipse GSR4 with turbo which was tuned by AMG. This came as a stock factory install and I never had any problem passing the car and it was a lot of fun to drive.
      Firstly, what all needs to be done to install a turbo, it is not just dropping in a turbo in the engine bay and walla, my car also has a MAF sensor, how does that restrict the turbo from working, or is there a way to adjust it?
      Does the ECU needs to be reprogrammed?
      On long run what effect does it have on a wearing old engine which you are trying to keep alive and running?
      Would I need new headers and exhaust?
      What kind of realistic minimum gains you can expect?
      How much would such a setup cost?
      Is it legal, will I have a problem passing my car in RTA if I do get the turbo installed?

      Hi Guys,
      I am new to Dubai and came across your website which looks so informative. So many wonderful posts.
      I have gone dune bashing with my cousins and I guess I have a dune bug that has bitten me. Now I want to get my own off-road monster.
      I am divided between the Toyota Land Cruiser 100 series and the Nissan Patrol and so far my cousins have been great help to confuse me even more.
      I would like to have opinion from the car gurus here as to which one is better for say 70% of on-road driving and 30% desert driving.
      What is power to weight ratio, and which one is better? Which one is more comfortable on-road? Which one is better in the desert drive? Which one has more after market mods available? Which one is lower on maintenance? Generally fewer headaches and more fun?
      I am eagerly awaiting your valuable inputs, and hope you will not leave me confused like my cousins.

      Dear All,
       
      Last time I had some timing issue with my Nissan Pathfinder 2001, R50 and the garage people wanted to make the readings on the OBD II reader, but they were unable to connect due to the connector cable not being compatible. They tried bring about 4 adapters but none of them worked. Anybody has any experience or ideas as to how I can get the adapter or a connector cable to be replaced which will solve this issue. Any feedback would be appreciated.
