Yes, there is both a crankshaft position sensor and a camshaft position sensor. But I would not focus on those for your concern. Check for air intake issues, crankcase ventilation issues, engine timing issues, exhaust issues, emission system issues. Hands on inspection is needed.

It is inside of the distributor, that thing the wire connector plugs into. Also called the distributor pick up. What is the trouble code(s)?

Let's get this cover off of here using our 8-millimeter socket. Now that that covers out of the way, if I was to follow this right here, and come along the backside of the engine, I'll be able to feel where the wiring harnesses that leads down to that camshaft position sensor. And I'll also be able to feel where the 10-millimeter headed bolt is.
It's not really something that you can easily see, and you might even have a little bit of a hard time getting to it. But, I'll show you it a little bit better by taking off the intake. You don't necessarily need to take off the intake. You can do this with something as simple as an extension, a 10-millimeter socket, and a 3/8 ratchet.
So now we got the intake out of the way so you can see exactly where we're gonna need to be. You don't need to take the intake out to get to this. Like I said, you can come right along the top of the intake, bring your extension down with your 10-millimeter headed socket on there. And we take this right off.
So reach down along the backside of that intake, feel with your finger, grab onto this. Grab it. Slide it right off. Now we're gonna use our 10-millimeter right here. You grab onto this. Sometimes you just got to wiggle it around a little bit to break it free. Now, sometimes the sensor back here is gonna be stuck inside the engine. If that's the case, you could try to come behind the intake with something that looks like this. Nice little curve to pick. Right down along the backside see if you can grab on to it, and just see if you can get it to come on out of there.
Sometimes, these will come right out, other times, you'll have a much harder time. If that's the case, and for some reason you can't get it out, I would go ahead and remove the intake system in which case we have a video that can show you how to do that. Give it a nice tug. There it is.
The next thing you're gonna wanna do is lubricate the seal right here. Just use a little bit of engine oil. Now, I'm gonna take my rag, and I'm gonna clean out the inside of that hole as much as possible. It's pretty nasty. Let's grab our sensor. So you just wanna push this down so it's completely level with the engine. Line up those bolt holes, and then we're gonna put our bolt in.
Grab your electrical connector, slide it in, give it a nice tug. That feels great. Let's get our engine cover back on. We're gonna slide the back side in so it connects into the hooks. And just drop this down. Now, you would just tighten up your mounting nut up here, mounting bolt. Give it a nice wiggle. Perfect.
