2005 Saturn Relay Repair Question
I have a misfire after tune up
What trouble code was found, P0300 or something other?
only one is misfiring i think
PO301, PO302... indicate what cylinder is missing.
i think p0302
That would be cylinder 2. Remove the spark plug and check to see how it is burning (what it looks like) and let me know.
Would using NGK spark plugs cause it to misfire should I use ac delco
No, that shouldn't cause the issue. They are good plugs. However, anything is possible.
