Okay so my car is running like crap sometimes it'll start right up others it struggles other its completely dead. Got battery alternator and started checked today and they all came back good.

Took it for a diagnostic, these came up.
P0036 - h025 heater control bank 1 sensor 2
P0140 - h025 circuit insufficient activity bank 1 sensor 2
P0833 - clutch pedal switch 2 circuit over?

Those are what came up, took it to Firestone comets auto care (I work for Bridgestone tires so I get discount there) and they said they can not perform any of that, it's over their mechanics heads.

So my question to you guys is what could I possibly be looking at expense and repair wise?? Are they going to have to do a tear down and determine the issues? I'm stage 2 with air box mod, clear image header and catless dp . I do have o2 sensor code for CEL. But it's been like that for years.

I'm in a huge bind right now with a breakup from my ex fiancée and having to move out to my own place and child support so I feel like I'm pretty much screwed with this car

 

Bump

 

Hmm is the car tuned? Or just gm s2

 

Just on GM stage 2

 

U check Ur vacume lines and all that..
Air filter in good shape...ext...

 

Yea everything is good

 

Well the first thing I would check is your front o2 sensor make sure the wires r in good condition and if so would just replace it with the oem sensor not the Bosch crap the last code maybe caused by keeping your foot on the clutch pedal while driving so fix the o2 and then reset the codes and go from there

 

Would me running catless and just being on a GM stage 2 kit have a lot of effect on my car?

Thanks for your input and help guys I appreciate it. I wanna try and check everything before I consider taking it to the dealer

 

Well car won't even start now. Won't turn over all it does is click. The battery starter and alternator were all checked out fine yesterday on their scan test

 

Those codes won't affect the problem you are having. The o2 codes are for the heater circuit that isn't working, and the other is the upper clutch switch, which sucks to change but only really affects cruse control

Google how to check for a parasitic draw and start there. Sounds like it may be your issue

 

The codes are for the rear sensor as well, not the front

 

Which is the sensor I don't have hooked up or shut off thru HpTuners ?

 

replace the second O2, has to be a AC Delco. Bosch doesnt read correct on the heater circuit

 

Have you checked your emissions fuse under the hood or all fuses for that matter.

I have some what similar codes and it ended up being a blown fuse. I always like checking the easy stuff first and go from there.

 

That def a good thought.

 

I will check fuses tomorrow and see about the o2 sensor. Thanks guys, but I'm still curious as to why my battery is getting completely drained but when I jump it and get tests done hours later they say my battery is good and everything else is good ( starter and alternator )
