Thanks

Apprec., now I'm ALSO getting a P0155!!

EGR?

Should I delete or...?

Codes appear after long idle; I also experience a miss/roughness at 5200 in 3rd, and is even more pronounced in 4th...

Anyone else experiencing this??

Any suggestions???

Thanks again for your time

P0155 is your drivers side O2 sensor....check wiring on both ..coolant and o2 sensor..chk and make sure you batt cables are clean and disconnect for 10 min. see if this clears the PCM

 

[chad9350]

Checked

ohm checked both 02 sensors, both are good...

connections fine,
reconnected and still getting the P0155


P0115 gone...

Alldata says possible EGR...

any other suggestions.

Thanks again for any/all info
