Problem - throwing CEL codes

My car will start easy early in the morning!.. But throughout the rest of the day it will only start on the second try!.. It is throwing these codes, P0340 Camshaft Position Sensor A bank 1, P2197 02 Sensor stuck Lean Bank 2 Sensor 1, and P0174 System Too Lean Bank 2!..

Any ideas?!?.....

Any Exhaust Mods?

Replace your crank sensor .. If it doesnt work you have a bad altenator.

I've had exhaust mods on it for about four years!.. Lol. And do you mean "Camshaft sensor"?.. Lol. Ya that's what I'm going to do tomorrow!.. Hoping its not the alternator!.. Don't have the cash for that on right now!.. Been reading up and seems others with that same problem and code, most cases been the alternator!..

Had same problem when I bought my gt
I got a new crank sensor and all codes went away you will have to loosen the ac compressor to have enough room to get the sensor out

From what I deal with at my work it seams to be the crank sensor is failing and for the lean that just could be a 02 sensor being thrown because of it or if you have a o/r pipe it could do that as well

I thought the same thing upon my search for a problem when mine threw a crap load of codes out of nowhere. I read somewhere - I can't remember exactly cause it was a year ago but people changed out the crank sensor and fixed the problem. So I did and it worked. The crank sensor is like 25$ and cam sensor is like 20$. Wither way I'm almost 100% one of the two is your problem

Been doing some more reading and seems others have had codes pop up similar to mine!.. They replaced the sensors and the codes still came back!.. Then they replaced the alternator and the codes went away!..

Seeing as I'm also getting like a "ticking" kind of noise that seems to be Coming from there, I think I'm just going to do that and see if it works!.. Also noticed this morning my lights were a bit dim for a couple seconds after I first started the car!.. Then I turned off my radio and heater and the lights got brighter and stayed that way, even after turning the radio and heater back on!..

I do appreciate everyones input!.. Thanks!..

Update!.. I went ahead and just replaced the alternator, no codes, no ticking noise, and runs like a top!...

If anyone else has this same problem I suggest taking a good look at the alternator first!..

Alternator!... I did a lot of reading on this and it seems that 9 out 10 times its the alternator!... I just simply replaced the alternator and now there are no more codes!..
