Does the car show any codes? Here’s how to check for codes if you don’t have a scanner.

You may be correct, bad injectors may be leaking fuel and fouling the spark plugs. If the injectors are original to the car they should be replaced under any circumstances. Do all the spark plugs become fouled with fuel or just a few?

Let us know what you find.
