Need help asap...trouble codes.

[BruhBrahBrad]

Ok so last Saturday I put in my new clutch, but I had to cut the egr tube going to the h pipe, cause it was welded. So i finished up the clutch, drove it.. it seemed fine besides that the pipe was rattling. Then I got the check engine light. I didnt check it until wednesday, cause I noticed the car stunk really bad. These are the codes I got: koeo 171 172 189 556 then koer 172.... so disconnected the battery last night to reset the codes, drove it all day today, this time I only got the 172 code back. It also has a hanging Idle, i checked for vacuum leaks, I couldnt find any. I also recently upped the timing to 13 degrees, but that didn't change anything, or affect anything.

Please help me diagnose this... It seems to be running through gas more too... any more information you need, I will try to answer to the best of my ability. thanks for any help i recieve.

172 - o2 Sensor sensor circuit indicates system lean (right side)

OH yeah... i know that thanks though, i have a list of all codes...

when I had those codes all I did was clean the maf. no more problems since

I think it has something to do with the cut smog tube.... Because last night I put a x pipe on my friends car, and we had to cut his too. now he has a light.

I don't see how the smog tube will cause any codes. the smog pump isn't attahed to a code. and it feeds the cats which are after the o2 sensors.

I do believe theres vacuum there.... it sucked my finger in.

I do believe theres vacuum there.... it sucked my finger in.

where? At the h pipe air pump fitting?

 

[BruhBrahBrad]

Where I cut the air tube. before it goes into the h pipe.

 

[beuchaw94gt]

Swap the o2s and if you get the other code for the other side you have a bad o2 sensor.

 

[BruhBrahBrad]

okay

but also tho, the o2s are new, and the car didnt do this till I took the h pipe off, so im thinking its a exhaust leak at the headers.
