Nissan Quest Wont Accelerate Beyond 15 KM/h ?? [SOLVED]

Sorry to hear that, OP...
I suspect: Canadian Tire...

I'm being serious - they could've done something to cause it -- and it MAY not be coincidence that this problem.is happening now... Eg ignition coil / spark plug change might not have been proper is my guess - got loose, faulty product/cheap plugs etc

Just posting to see if you can figure out and undo what they did or inspect things visually to see if there seems to be anything wrong first... I'll let others try the more complicated stuff

My next guess is your alternator causing these other issues as it seems to have impacted electrical issues eg battery - but afaik, at least the battery symbol should light up in your dash if that was a problem

I hope you've read enough here for you hopefully not to take it to CT in future repairs/maintenance work...
Good luck!

Friends don’t let friends take their car to Canadian tires (aka Crappy tires, China tires).

The limp mode is on most cars. Nissan seem overly complicated for jap cars. For example some models have 5 computers!

Limp mode is so you can take the car to safety / mechanic. But there is something detected that is causing it to go super slow. My guess, it's computer related.

beat me to it.

The cheapest sparkplugs in the world would not cause this problem, so I would rule them out, but maybe (just maybe) the wrong Ignition Coils would.

I also think it is computer related, but there should be a code.

According to this article #9 is what you just replaced: https://www.wheelsjoint.com/nissan-ques ... to-fix-it/

With spark plugs, I tend to go OEM and that is what I did when I replaced my plugs on my 2012 Camry at 180K at the dealership. The cost of the plugs with labour were within a few bucks of Canadian Tire, but I feel more comfortable going to Toyota then Canadian Tire.

I'd take it back to Canadian Tire, talk to the Service Manager and tell them what happened and they should resolve it. If you have have any issues with the service after things are resolved contact 1-866-746-7287 and tell them what happened and they can reimburse you something.

In the future, take the vehicle to a GOOD private mechanic or the dealership. It may cost you the same or more, but these types of things may be avoided.

Wow, you wasted a lot of money replacing random parts without knowing the actual cause. I'm sure CT told you that would definitely fix it. How much did they charge you?

Most likely there is a loose or missing wire or ground or the original problem has become worse.
Try disconnecting the battery and fully charging it. Reset the ECU learning if you can.
Unfortunately you're stuck with crappy tire now, unless you want to pay more to have a proper mechanic diagnose it.

Thanks for the info. Well that's depressing to hear about Canadian Tires. I should point out they originally quoted me $1400 to replace all my spark + ignition but i said NO instead I'd supply them brand new parts ordered off Amazon for the car and then have them install them. They agreed. The final bill with parts came to $600. Again the vehicle ran fine for 2 weeks and now this.

I will take hightech's advice and bring it back to CT to see what they say.

I'm situated in London, ON. If one want's to recommend a competent HONEST mechanic i'm all ears.

Ok, well that's good you didn't get hosed to badly.
See what they can check for you. At least their own work under warranty.
I suspect loose ground, or the original failure hasn't been fixed. Proper diagnosis needed.

Were the parts you ordered quality parts? Or no name Chinese stuff? If cheap, the could have failed already.

OP, your car is in limp mode. Most common cause on VQ35 is the MAF sensor located in pipe between the throttle body and the air box. The sensor is either gunked up or is damaged. Try cleaning it with throttle body cleaner or it may need replacement if it's damaged.

So you are saying, instead of $1400 for parts and labour at Canadian Tire, you paid $600 TOTAL for parts and labour using your Amazon Parts? That is a hell of a price difference! What parts did you get compared to the quality of OEMs or Canadian Tire ones?

Hopefully you don't get into a situation where Canadian Tire can point you to having bad parts, and the parts guy saying they didn't install right.

When I get price quotes that are that far apart, I question the quality of those parts as $800 difference for plugs and coils is huge.

As for recommended mechanics, here is who CAA recommends:

https://www.caasco.com/auto/caa-approve ... ity=London

The APA list is as follows: https://www.apa.ca/readarticle.asp?id=1223

Dead battery - computer controlled automatic transmissions may not operate properly without good voltage.

Swap in a known good battery plus check the alternator voltage - see if there still is a problem

Just thinking out loud... is this one of those problematic Nissan VCT transmissions?

For the record here are the Ignition Coils and Spark Plugs i purchased off Amazon.ca:

Bravex Premium Ignition Coils

Autolite XP5325 Iridium XP Spark Plugs

They mentioned they replaced the battery 4 months ago. That being said, it could be low on charge. They can get this charger to fully charge the battery: https://www.canadiantire.ca/en/pdp/moto ... p.html#srp

If the alternator was bad, I would think the Battery light on the car would light up indicating a charging problem.

So what you're saying is if the battery has poor voltage even while the car is started it still could affect the acceleration of the car while driving?

Anyone want to recommend a battery tester? Or will a basic multimeter suffice?

The best thing to do would be to take it to a trusted mechanic who can PROPERLY diagnose it

Do you still have the original parts? It's unlikely all (if any) of your coils needed replacing. I've never heard of BraveX.

Yes, low voltage could cause odd problems. So fix that first. Partsouce will load test your battery for free.
