A couple questions!!??
 

hi, a couple more question again=.=....thanks everyone..

what is the tire pressure we should have regularly? or to save more gas for city driving 90%?

how much is it to have shop change coil and wire? my spark plug got changed already...

and for doing MAF sensor cleaning i am really scare i will mess up the car i did search here....

air filter would K&N work better? or should i just take it out and clean it?

THANK YOU VERY MUCH...i am still concerning about the 10MPG city driving....

i love the car a lot...you guys are really awesome, i found a lot of information here....

I run 34psi in my tires I believe 32 is recommended..but I like 34 for some reason
Changing coils and wires will cost u quite a bit...best to buy the parts from a vendor on this site and do it yourself it's not hard just a few bolts on the coils and unplug the old coil and plug the new one back in...and wires is easy as unplug and plug new ones back in....

Max time I would say is an hour for a person not knowing tooo much....but someone that's done it a few times....30min MAX....
