Drove the car yesterday all day no problems no check engine light nothing. Came home and parked it. It's about 11:20 AM and i go in today and start the car. Started up. Idled fine. Check engine light is on. Scan the car with my dual aeroforce gauges and pull 10 codes. Maxxed out. Turned car off and pulled out the obd2 scanner to scan codes and get a description. Got all 10 codes but were repeated. Ho2s code both banks. Evap system not opening. I clear the codes. Turned the car on and the homo is surging. Starts , surges, stalls. I try several times about 6 times to get it running and still stalled. Pulled codes and got 1. Started car and it ran. So parked it and took old faithful to get some mcdonalds.

P0030
P0036
P0102
P0443

all codes came together basically. Check engine light aint on right now but i got that.

As for mods:

GMS2 pakage (injectors pully etc)
ZZP S3 FM heat exchanger
AEM cold air intake. not a full intake but its w/e. came with car.
ZZP 3 inch DP catted
2.5 Catback megan

any help is appreciated. as for why all codes are active at same time is what bogs me. no way a full system took a crap overnight on me. and the dealer where i bought warranty at is about 1 hour drive.

 

P0030 HO2S Heater Control Circuit (Bank 1 Sensor 1)
P0036 HO2S Heater Control Circuit (Bank 1 Sensor 2)
P0102 Mass or Volume Air Flow Circuit Low Input
P0443 Evaporative Emission Control System Purge Control Valve Circuit

If I remember reading this right from before there might be a short, all of these stem out of the ecm and work together at the same time . This might exclude the MAF I can't really remember, but could be the MAF causing all of these problems.

 

yes i know that. what is the real culprite to be causing all of them??????????? anybody experience this? i dont want to diag all curcuits outside in the cold

 

i would try disconnecting the evap solenoid from the blower and plugging it

 

Location of that?

 

Check your emissions fuse Luis, it's probably blown. Then check your o2 wiring and make sure it's not shorting out on anything. I've seen this happen to other people before

 

thnx matt. i was searching it up just now and i will be checking that out. as for 02 well i wish that bitch good luck lol. remember i got the zzp downpipe so i put 2 defoulers in it. 1 is honed out and the other is not. and thats how i made my home made defouler for the 02 sensor code. cant wait til that block gets deleted in the tune. im not worried as much now. car runs and drives so i can go to work lol

 

ok fuse was blown. now i gotta find out why it was blown.

 

You put a defouler on your primary and secondary o2 sensor, did i read that correctly? If you did take it off, you don't want a defouler on your primary o2 sensor.

 

secondary sensor. the useless sensor. i dont mess with the 1st 02 sensor ever. still want to know why the fuse was blown.

 

Ok just making sure lol you never know, some people do the darnedest things. It's usually the o2 wiring shorting out, wrap it up in heat shrink or electrical tape and make sure it's not rubbing against anything

 

from which sensor though. bank 1 or 2. i saw the first 02 sensor hanging around hitting the rear tranny mount. that may be a reason why.

 

That's probably it

 

we only have one bank, and primary and secondary sensors.

 

Ill wrap it up during the week. Gonna be upgrading mounts so ill take care of that then. Damage is prolly done already
