I need help figuring out what’s wrong with my 2005 Nissan Maxima 3.5 SE. I’ve replaced every main sensor, transmission, both valve covers, gaskets, intake, intake filter, and spark plugs. At 3-4 thousand rpm’s it won’t accelerate, below 3 thousand rpm’s it’s fine but no acceleration above 3 and it makes a lot of noise from the engine with a clicking sound. You can feel the fuel going into the engine but the engine struggles and dosent accelerate. Can anyone please help? Also no check engine light.

 

Spark plugs and coils, recheck them. Did you cross the plugs???

Is that the reason why you did all that surgery, or normal before surgery?

Give us more details

 

Clogged cat?

 

The reason for all the surgery was to stop an oil leak, and the spark plugs needed a change. Yesterday I got a check engine light and it was random cylinders misfires P0300, the only thing I did not change where the ignition coils. I’m going to change all of them their like 60 for all 6 on Amazon. Before it was normal apart from leaking a lot of oil, I checked all my wires and spark plugs.

 

Our maxima are “temperamental metals”

go with the OEM plugs and save the headache.
