don't have my manuel how many spark plugs are there in a 1997 cutlass supreme oldsmobile. need to change them all v6 engine. what is the best brand to buy thank you
You do not need to gap double ground spark plugs. Just put them in right out of the box, but note how they are gapped. As the plugs wear out, the gap increases, so when you notice the gap increasing, change the plugs.
If you need to ask this question I would recommend getting the plugs done at a mechanic.
a/c delco is the best
Check for the possibility of one or more bad spark plugs. (A loose plug might also cause this). On a 1995 Tercel, plugs are not too difficult to replace yourself with the appropriate tools. You'll need the appropriate socket and a long adapter since the plugs are positioned lower. sg
u need to quite driveing
Check the Vehicle Emissions Control Information ( VECI ) decal located in the front of the engine compartment ( it will show what type of spark plugs to use and the spark plug gap )
The spark plug tubes need replaced.
If the engine does not have spark plug wires, then the plugs are located directly below ignition coils on the top of engine next to valve covers. You will need to remove coils to access plugs below.
