Question about 2000 Nissan Maxima
When i accelorate i hear pinging like metal cans i had my lifters checked there ok what should i do< please help
The MAF (mass air flow sensor) is a common problem on this car. I had a mechanic change mine for $300 you can do it yourself for $100. It is the big "box" right after the air filter.
Can't be sure it is the problem, but my car had pinging, rough idle, and it would heat up.
Another common problem are coils - this usually has the check engine light one (unlike above). Some dealers want to charge you $600 for parts, and $240 to install them, but if you shop around/bargain you can get them for $350 and install yourself in less than 30 minutes. They sit right on the spark plugs (see your owner manual for under spark plug change). You pull them off and then disconnect from wire by pushing the connector with a screwdriver where there is a little arrow. Very simple and quick. The dealer also wanted to charge another $120 labor for changing the plugs (even though it slightly harder than the coil - need a spark plug socket which most DIY have). I did both in 45 minutes and saved $360 in labor and over $300 in parts! You don't get greasy and grimey like fluid changes!

What you are referring to is commonly called "pinking" - or pre-ignition.
Lead tetraethel used to be added to prevent this, but is now banned. Other additives are used instead but are less effective.
I think your engine could benefit from a new airfilter, properly gapped plugs (if petrol), and a tune to reset the timing.
This should cure the problem for you.
(If this solves the problem, please remember to rate so that others can benefit from this advice. Thanks)

It could be a simple lose heat shield for your exhaust manifold
