Default Error codes P0123 P2074 & P0068 Please Help!

Hi Everyone! I'm still a general newbie when it comes to forums but am really glad I found this one. I've been a Pt cruiser owner for 6 years now and regret not joining this awesome community sooner.
Now that my 07 cruiser is closing in on 100k miles (96k at the moment) it's sure giving me plenty of opportunities to get connected. First my ac compressor clutch, then my radiator fan, and now I'm having a problem with what appears to be my throttle/acceleration.
My car has a tough time accelerating and jerks at times. furthermore, at times it flat out stalls out when I'm driving slow (under say 15 mph. When the car does stall, restarting the car has fixed the problem every time so far.
I re-replaced my CAM sensor (it was under warranty) after doing the key dance and getting the codes P0123 & P2074 (not the code p0068). After Replacing the CAM sensor the check engine disappeared (and the key dance didn't turn up any codes) but the symptoms didn't go away.
Today I stopped by AutoZone and had them read the codes on my PT. The codes came up as: P0123 P2074 & P0068
Would you suggest I replace the TPS ($80) and MAP sensor ($20)? replacing parts unnecessarily can get expensive so I was hoping for suggestions before making any discussions.
I'd appreciate any suggestions
P.s. I have a 2007 base wagon

That's' your choice, but cheapest fix is probably best.
You might look into the Idle Air Control Valve also, it can't be cleaned like in earlier models...anything 2006 & up it has to be replaced. ($50)

I would suggest the first thing you do is buy an OBDII Scan Tool
Harbor Freight has them for a good price.
Search results for: 'obdII scan tool'
Do not buy just a code reader.

You need an OBDII Scan Tool to reset your engine trouble codes. Any time you repair or replace a component in the PT Cruiser you need to reset the engine trouble codes by using an OBDII Scan Tool. Doing the dancing key routine or unplugging the battery will not do it.

After you have done the above then you can drive the PT Cruiser and see what engine trouble codes come up. When you do then post it here and we will respond to it. Otherwise you are wasting your time not knowing what is going on.

"I re-replaced my CAM sensor (it was under warranty) after doing the key dance and "
Some times its easy to read over a post and not notice or get "Just the facts"
I see Warrantee, was your car under Chrysler Warantee and replace the CAM sensor or did you replace it with an after market sensor , then return it for another one?
Working on 100,000 miles, have you replaces plugs, wires, make sure they are pushed in all the way in the coil, cleaned battery post to perfection, make sure they are tight. Oh yes, are you considering the timingbelt, tensioner, water pump,idler maintenance before it breaks?

Thanks for all thr feedback. I ordered a OBDII Scan Tool and am waiting for it to come in. I also found a tps for $20 so ordered it. It's worth a shot for 20 bucks.
My cruiser had an ongoing problem with otherheating until recently. Do you think that could've broke a sensor?
My car is not under warranty but the CAM sensor is under a warranty From AutoZone

I would suggest only buying Mopar brand sensors. The PT Cruisers don't like aftermarket sensors.
