hello all, new to the forum. Did some research here but may have overlooked but i just had 8 new injectors put in via the dealer on my 01 at 86396 miles and currently have 87748 miles on it and am getting an p0089 code via my CTS tuner. I cleared it but it came back. When i went out to start today to confirm the code to see how to fix it, the "check engine light" went away so it is inter mitten. I thought about getting back with the dealer since i didn't have this issue until all 8 injectors were replaced. Any suggestions or how to resolve this issue. I am currently heading to my daughter/son-in-law on Friday and not sure if i don't get this fixed now, if i will have problems when i head that way this Friday? tks
