Need help with some codes....gurus help

Hi guys...finished the replacement of coil spring and drove to auto zone and had them pull the codes for the "check engine" light....this is what I they said...
PO171.....system too lean (bank 1)

P0340.....camshaft position sensor circuit malfunction A-Bank 1

Told me the $36.00 position sensor mounted under the coil pack would remedy this.......
any ideas or comments? BTW 95 3.8 liter

Thanks,
Will

What's up Justin......getting used to the 6 cyl. is a trip...lol.....I put the new spring on, went to JY and got used kickdown clip..car engine runs fine.....goes down the road fine but when I hit the brakes the car shakes a little and pulls to the left.....car sat for quite a while....I know it hasn't been driven since Jan.....don't know if the caliper is tied up.....I checked the rotors and no grooves in them....but you know how that goes...could be warped.....of course there are a few little issues like the pass. window motor does not work....so I have the panel off...and the drivers seat is broke back so I have the gangster lean going........no issues.......to be expected that I will have to do some work but all in all worth what I paid for it........(esp. the Cobra rims and Goodrich tires.......they do hook up better on the street then the cooper zeons I traded for it.........and it has headers on it???????????????????but I did notice on the receipts for the motor and trans something about manifold bolts having to be drilled out....I'm wondering if it was just cheaper to put the headers on......Police chief's wife bought it new....hard to believe......lol

I have really been thinking about the brake upgrade on the GT..........really.......just dragging my azz......when I am at the track and slowing down I "really" think about it.....soft brakes are def. and issue with us isnt it. I may just get some generic rotors and pads tomorrow and throw on just to see......hoping it's not the caliper.....but if so no biggee........I'll have HEATH and JAKE help me out on the "MOUNTAIN"..... ....what would you suggest to clean the MAF with......electrical cleaner from auto zone..

You've got to remember, if it involves me......it's gotta be out there...holding off on the window....found out that both front springs are broken and that is why it shakes...will be getting the other spring from the donor vehicle....that's two cars I've bought in two weeks with broken springs... I did get the new cam pos. sensor and cleaned MAF and engine light was off when I plugged the batt in and drove it for a little while

Quick question.....if it was the pass. switch then the driver's switch would work the window correct.....so chances are it is the motor on the window........
and Justin.....I was a stunt double for Jake......and I told Heath that I was "driving".......

Well, got the second spring replaced and drives a lot better......got of work at 10pm and felt like working on the car....
I'll address the window later this week....
Thanks JT and Justin...
