What are the best spark plugs to prevent rough idle for a 1998 Chevrolet silverado 5.7?
Ac delco. Always ac delco with gm vehicles.
Options are like noses. Everybody's got one.
Michael Jackson didn't. LOL
Thank you and ha funny
If you think about it, T.A. Michael Jackson had quite a few. Including the one he kept in his pocket.
The split fire ones should be good for it. Always worked for me.
BoholMark, true, very weird and a lil twisted but, true. BAHAHA
I recommend AC Delco. If you have a rough idle unless the plugs are very old 50K plus miles, I would suspect a problem with something else. do you have any engine lights coming on? Other than a misfire from plugs, wires, cap - etc, it could be fuel mix/delivery. Check for vacuum leaks...
Any top manufacture makes good plugs. Just make sure they are for the heads you have. When I had my Edelbrock aluminum heads put on my Corvette, the reach needed to be longer over the stock GM iron heads. The poor little guy who put the plugs in, put in what GM called for in the stock heads. I was detonating inside the plug hole. It worked, but could of ruined the new $ heads. Clean the plugs, gap them correctly, and see if that helps. Next would be fuel flow, then electronics to check. Wires also wear out sometimes through heat, oils, fumes or wear and tear on the wires.
Yes I have the check engine light on & it gives me the code P0300 which is a misfire but I also got the code P0174 system too lean bank 2 by the way I changed to new fuel filter new spider injectors new rotor and distributor cap , I was told to change the spark plugs ,, any ideas
Plugs and plug wires both.
