Check the computer
Is the remote's battery dead?
check your relay or your fuses. if the fuses are good replace the relay (under 10 bucks) if things still don't work try replacing your switches.
if the picture is not on the cover and you dont have the owners manuel go to autozone or oriely and buy a haynes manuel it will be in there
well, this is what my mechanic told me when i had this problem (still have it) with my 1994 Nissan altima: the altima's alternator isn't working well. so, the battery isn't well supplied... Solution: replace the alternator immediately or dont drive the car until u do so less you make things worse. bajah
in the altima, the radiator plug is at the left side of the bottom. if your planning to drain it, be very carefull because the plug is kinda fragile since its plastic. dont over tighten when putting it back in :)
check switch on driver control panel
Your best bet, if you dont know, take your car into a certified Nissan Dealership. That way you dont mess your car up as you try to find/fix it. Most of the time the o2 sensor issues arent a HUGE deal. but it is recommended that you take it in as soon as possible to be on the safe side
20 inch will fit perfect but dont put any higher cause its going to look ridiculous
dont do it yourself!! take it in i know its going to cost atleast 80$ but its better someone that knows what to do, than having to think oh what did i do wrong?
Get a very good mechanic and dont plan on getting your car back the same day. Or buy a new gasket and remove the intake and diy.
dont no
