Re: Help Pls on Diagnosing a Rough Idle (RIPP SC)
Hi Jmone! Looks like i have the same issue with my 5.7 Hemi after RIPP SC.
Have rough idle(but not so bad) it throws RPM on idle from 600 to 700. Also have Check Engine Light came in with P0172, P0175 as both Banks running too Rich.
My mechanic said that he checked for vacuum and boost leak as well but the codes keep coming and nothing changed. (Looks like i need to change the garage.)
Today The engine also running very hot up to (235F) once gets a boost on about 2000-3000RPM but never gets below 210F, even with 180 degree Thermo installed.
Just wondered if you have fixed your issue and what was the solution?
