Engine seems weak

[DStockton]

I have a 07 denali with the 6.2 and it seems like it doesn't have the power it used to have. Was wondering if something like cleaning the injectors or something would help.

How many miles?

 

[DStockton]

90k

I take it you have done the basic maintenance...... Plugs etc?

 

[DStockton]

So just do the plugs and wires pretty much?

ALso which plugs do everyone like the most?

 

[Goodinblack]

I would put back in all the stock stuff for the plugs, wires, etc.

It was good once with it and it can be again.

AirFilter, I would put in a non-oiled hi flow unit.

You could run the gas tank injector cleaner once or twice, I would NOT over do it though.

Damn 90k for an 07... Id get what was stated above and also maybe check the fuel filter

So would you not recommend a k&n air filter?
