2002 Monte Carlo 3.4L but more of a generic question
Owners manual says spark plugs are good for 100K.... Platinum plugs...
I just replaced mine at 57K, they looked not too bad, a little worn. But
100K is probably stretching it.
What would be a conservative service interval for replacing spark plugs???
( 2/3's highway and 1/3 city driving).
What would be a conservative service interval for replacing the WIRES
as a scheduled maintenance item ??? Do wires last longer than
today's spark plugs, or should they both be changed about the same time ??
Finally, the Fuel Filter..... Haynes says every 30,000 miles or 24 months as
a general rule applying to several engines. (3.1, 3.4, 3.8) Alldata,
specifically to a 3.4L says there is not a recommended service interval but to
only when fuel delivery starts to be restricted.
What's your take on replacing the inline canister type fuel filter under a
maintenance schedule ?? .
Thanks in advance !!
