Considering your 2002 has the old fashion cable connected to the throttle body, I’d have to go with no.

That’s said, not cleaning the throttle body (TB) will eventual cause problems. Many people have beat their heads against the wall replacing items only to eventually discover is was simply a dirty TB. It’s a five minute easy to do maintenance item that needs to be done regardless, so why not just do it.

And if cleaning your TB doesn’t fix your problem, I’d look at the MAF sensor next.
