Chirping when accelerating

Chirping when accelerating
My engine is making a chirping noise and, for the life of me, I can't figure out where it's coming from! It only makes the sound when I'm in gear and accelerating around half throttle or better. It sounds like a cricket chirp, and it seems to get faster and higher pitched as I give it more gas. For a while I thought it did it after reaching a certain RPM, but I don't think that's the case anymore. Sounds to me like it's coming from the drivers side somewhere, but it's really hard give anymore detail because I can't hear it unless I'm driving.
Don't think this is related, but I've also had some other problems when I start it. Sometimes when I crank the truck, it seems to be sputtering a little bit during take off. Almost like it's missing or something. I was pulling out of a convenience store the other day, and it was running rough again so I just pulled over on the side of the road and killed it then turned it over again and it seemed to be running fine. Like I said, not sure if those could be related but I figure all the info I can give will help. I really don't know much about the inner workings of engines, but I haven't really had any major problems other than these things listed.
2003 Ranger Tremor w/ approximately 85k miles on it.
Anyone got any suggestions? Can someone point me to a related post? I've spent around 3 or 4 hours perusing through this forum and I haven't found but one or two posts that seemed to be the same issue. Thanks in advance.

i would be sure to check a/c clutch if you have a/c. as it engages and disengages with the compressor the sudden shift from no torque to +2000 rpms may have toasted your a/c clutch bearing and its not uncommon. i would focus there just to rule out the easy fix of a new compressor because i do not believe the clutches come off

oh man! one person got this right...your sputtering and the squeaking are related...buy the tool, read my how to, and replace the cam synchro and sensor

cam syncro usually makes a chirp at idle - and stops or gets quieter when accelereating in my experience.
if it is the cam syncro - no need to read write ups and make it harder than the job really is.. just remove the bolt and put the new cam syncro in the way the old one was. You can use a permanant marker to make 2 small dots that will line up if it makes it easier for you. the teeth engage and leave the sensor to positions that "click" into place - so its not like you have infinite possibilities or anything like that. your looking at around a 10 minute job your first time if you've done an oil change or anything like that before.

The sensor can only be installed on the synchro in one direction, there is a notch in the synchro where the hall effect sensor sits.
The synchro, just like a distributor can be installed in an INFINITE amount of spots. If you "slap" the synchro in the hole, your PCM will have to make up for your error of installation, and if it is too far off, will cause a bunch of driveability problems and DTC's related to injector timing.
Also if you had read my how to, you would know that i dont over analyze installing one of these...I have installed atleast 1,000 cam synchros on 3.0's 4.0's 3.8's 5.0's and any other Ford motor that uses them.
Id REALLY like to see you do a cam synchro on anything but a 3.0 faster than an oil change...

the housing will what? dude - bolt on the sensor to the damn syncro the same way it was facing (one of two ways) and slap the ******* syncro in the hole. if you marked the position of the unit with a marker it will be easier. Hardly a DIY. you can do this quicker than an oil change.

^ thank you - i do agree that over analyzing and tech geeks are another form of whining!
For what it's worth - the DIY is a good one; I did refer to it before taking on the job to see what it would be like.
The pictures were great and the grammar was good
