What are the symptoms of bad spark plugs? Never changed mine. Is it something simple to do with a usual wrench set?

 

hmmm, how many plugs are there need to be replaced, and how much for each one? I wanted to get them at like autozone or some aftermarket place.

 

you know, lately I feel that my car is losing power in pickup and bad auto shifting, maybe its the spark plugs? 88k mileage and never changed them (year 99)

 

Does bad spark plugs have anything to do with "labored" starting or can this problem be attributed more to a weak battery?

My opinion you should give the car a complete tune up including plugs, maybe even wires.

 

well I just want to install this stuff myself, in like 2 weeks i ll get to the car and try to change the wires and plugs, isnt this the entire tune up? maybe change fuel filter... etc. Also I just replaced alternator last week (got aftermarket rebuilt alternator), and now when i m parked the alternator barely produces the normal volatage however when i press on the gas pedal the alternator functions at normal output level. Is this normal for an alternator? Or should i get new one (got 1 year warranty). Could this be tied to my symptoms above?

 

Correct, I dont get where people say to change the wires, im guessing they have never opened there hoods?

either way, get the coppers, change every 30k.. The platinums are overpriced for just so you dont have to change them till 60k, but then again u pay about $7 extra than a regular copper plug..

 

another thing please, it says each spark plug must be torqued in at 22.4 lb? how the heck you know that u screwed it in at that ecxact torque? (newbie)

 

Buy a torque wrench and torque it to 22lbs.
