Poor performance

Poor performance
Just started yesterday; I punched it to make a light and car started to shake and it felt and sounded like it was running on 5 cylinders. No power uphill. Let it idle for about 15 minutes and it was fine. Took it to work this morning, started out fine then about halfway to work it started acting the same way as yesterday. No CEL!!!! Waddya think??

Yeah, I know. Haven't had a chance yet. I thought I would throw it out there to see if I could get some ideas. Usually when a coil pack goes, the CEL will light. I have to use my code reader and see if there are any hidden codes.

Check for the obvious KS code (it won't trip the CEL) too.

Not entirely correct, at least not in all cases. Some vehicles use the primary winding to measure the collapse of the field in the secondary winding. You can also see this with an oscilloscope. This will tell you if there is a break or short in the secondary winding.

Yes, still have the 95 Max; just turned 191,000 miles this morning!!!! I finally had a chance to use my code reader on it yesterday and it called out the P0325, knock sensor. Car is still running fine and no CEL. Could that code be caused by using lower octane fuel??

If you're getting nothing but the P0325 cel code then change that knock sensor. Your engine will run much smoother. I inserted a high priced OEM knock sensor 6 years ago but if you want to save money then buy one off ebay. I've read on this forum that those ebay knock sensors perform well.
Running regular fuel in your engine is what wrecked the knock sensor. The higher octane gas you use the longer that knock sensor will last. Our manuals suggest using only premium gas.

And make sure your car is in tip top shape. Good air filter, fuel filter, clean oil, good PCV valve, good coolant, clean TB, clean IACV etc etc. All these things will help give you the best mileage possible.

unless your driving with a 50 gallon tank, just use premium anyways. Like the Wiz said, there is only literally $3 difference on a FULL tank of gas and your getting better performance, better milage, and a piece of mind. Not to mention your manuel calls for it. You CAN afford premium.

if cost is your highest priority buy a Camry or Corolla.

Hope you learned your lesson - and that lesson is: Don't EVER admit to using regular 87 octane gas in your Maxima on this forum!!! Some of these folks are fanatics on the subject!! But know - you are not alone!!
