Hey everyone! Just bought myself a 2012 Chevy Tahoe ppv 5.3l with 75k miles on it about a month ago. Drove it from Miami to Greenville sc with not a single problem but within the last week(about 1200 miles later) I’m randomly getting “reduced engine power” with no throttle repose at all. I’ve seen others with the rep diagnosis on this forum but haven’t found anyone that is having complete throttle loss. When I scan it the code I get back is p0606. If I clear the code all is good and she runs fine, until it happens again. I read it could be a possible ground Issue so I removed, cleaned and replaced all grounds with dielectric grease. If anyone has had this problem I’d very much appreciate your input. I’d hate to go to the dealership and have them replace the ecm/pcm and it be something else. Thank you in advance!
