Re: Tune up questions
just slowly release the connections with a rag covering it to keep it from spraying around.
PCV valve is in the driver's side valve cover.
A 1997 should have the following changed:
Fuel filter
Spark plugs AC Delco Platinum only
Cap & Rotor
Air Filter
PCV Valve
Plug Wires
Transission flush and refill and a new filter
Differential fluid and transfer case fluid change
Also IMPORTANT: Swap things one at a time, don't rip the cap and rotor and plugs and wires off all at once seeing two of the plugs on the driver's side have swapped connections on the cap.
