hey everyone

i'm approaching 90K on my engine (GA16DE 1.6 in a 200SX SE)(almost 100K on the car) and Im concerned that I may need something. recently I've had my fuel filter changed, about 1 1/2 -2 years ago I changed my wires and plugs.. No real maintenance has been needed. oil changes have been kept up with. The car runs fine but over time, I've definately noticed loss of power, and hesitation -Especially in the heat of Florida summer. If I get on it hard or even medium I notice the gurgling fuel noise which is my fuel pump right? So should I just replace it now or am I good? My mom used to have a 88 corolla that gurgled like that for years and the fuel pump never wound up dying.

so why the loss of power and what can I do about it?

do I need to have any maintenance done at this point?

how about my cooling system? never overheat but should it be flushed or something? (I really don't want to touch it if its not really necessary)

My temperature guage has bounced around since my engine was changed, its never been fixed but and it does give temperature readings. this cannot hurt anything important right?

I really appreciate your advice guys thanks
