My humble opinion, I love the shotgun approach. I have a cooling issue, I'm going to go through every piece of the coolant system ..... I get it I could diagnose it & find the T-stat bad ..... In my mind I'm going in and flush the radiator, replace the water pump, all new rubber hoses .... I want it all replaced.

Imagine here in west Texas at 108 degrees & a hose blows .... you call a tow truck but are sitting on the side of the road with no water for a hour while waiting for a tow truck.
Seriously it could be life threatening.

Same issue with a ignition problem ..... We can play around and find if it is a crank or cam sensor .... If one is wore out the others are not far behind. I replace the crank, cam sensors, plugs, wires, coil ..... I replace it all. Is very cheap compared to a tow truck ..... I am a parts cannon & proud of it.

this is an intermittent problem. Everything seems to function normally,
If the Cam sensor goes bad the engine will run, but will cause issues. It will stall occasionally while you drive ......
Very possible a cam sensor is all you need. ..... While it works from the computer .... it does not stop the engine from running. Just runs poorly.
If the Crank sensor is bad, it stops the engine from running. ..... Just saying.

I apologize for being a bit abrupt yesterday with suggesting to just replace it all.

IMHO, I fought the exact same issues for a few years while I was dragging my feet not wanting to learn modern mechanics.
My 1993 caravan would die sometimes when coming to a stop sign .... not always, never while driving .... just when coming to a stop and again not always but more often if the AC was running & engine under a load.
I was trying to troubleshoot many things like the IAC, or I removed the throttle body & cleaned it I was a dog chasing my tail

I eventually found it was a bad cam sensor causing the problem. The engine will run, but will cause some issues like you describe ..... Then next the crank sensor went bad.
When the crank sensor fails, the engine will die & you need to call a tow truck. ..... Last week it was 108 degrees out, I do not want to be sitting for a hour waiting on a tow truck.

Years ago we would do a tuneup on our cars, points, plugs, wires, cap, rotor .... we just replaced it all.

Today we have a crank sensor, cam sensor, coil, wires, plugs. ..... I figure if these parts have enough hours on them that one fails, the rest are not far behind.

It would be nice to determine the exact issue, and if it was a cam sensor like I suspect ... I would check codes to confirm it.
I simply would not change the cam sensor. I would do the shotgun approach & change the whole ignition system at the same time. Avoid future breakdowns on the side of the road.

My fathers '97 Grand Voyager 3.3 has been experiencing a fairly intermittent stalling issue, while driving. Happens most frequently when slowing down to stop, and sitting at traffic lights, or sometimes just driving around town. Will not stall on highway, at consistent speed.
We are not talking a no start issue .... it is the engine stalls/dies when the van comes to a stop.
This is exactly how my van with the bad cam sensor acted. I would drive it out of town all the time ... sometimes coming to a stop sign it would die .... always started right back up.

It was annoying, but never life threatening .... just a head scratcher.

I honestly think that a 1997 caravan with unknown maintenance .... dies at a stop sign but starts back up ..... a tuneup is not out of the question.
