3M fuel system tune up

Is this worth buying? Whenever I get an oil change this is always recommended, ive never had it done and I have that warm start issue. I watched a video on how to do it correctly looks simple. Opinions pleez.

See what kind of warranty comes with the service. By way of example, two years ago my dealership performed a BG Products "upper engine" service, and it whacked my throttle body out of alignment. Fortunately, BG stood behind their warranty and paid the dealership parts and labor on replacement.

Is it worth it? IDK... what I thought was pinging was actually the idle tension pulley and AC pulley slowly getting more noisy over the years. All in all, having the service could (probably) only help rather than hurt.

I also SeaFoam once a year, and run fuel/injector cleaner once a year... so I imagine my internals are stupidly clean.

Maybe I should just do seafoam since people have had success with it. Ive read to use a non abrasive cloth when wiping out the throttle body, so can I use a microfiber cloth?

The TB on our cars is very sensitive, so if I were you I wouldn't touch it. In fact, don't even look at it hard.

There are dozens of TB threads, and although opinions always differ, the general consensus is to leave the TB alone. If advanced search ever gets fixed , you'll see what I mean.

Ive read the threads and these are the only 2 ways that solve the warm start issue. I sick of starting my car twice sometimes three times just because its warm.
