08 HHr ss feling a skip at 40 or so goon at high speeds
I have a 08 HHr ss automatic, love the car, but seem s to have a miss or skip at about 40-60 intermittingly. Also there is no codes. Any real ideas as to what could or may be the cause for this. I only use 92 or 93 octane fuel also new plugs at 8 months ago. Boost is normal power still strong, this is strange for me need some insight "help"

Yes back to the help desk! The LNF s only like the AC Delco plugs it seems, I'm sure others could chime in to dispute that but the question remains, what brand plugs do you have in there now?

Now myself I have two tunes on mine the GMTU and Hp tune I run NGK iridium step 2 colder plugs with a 30-32 gap and my car loves them and runs real good with that selection my car did not like the stock AC delco plugs at all and did kinda what your explaining. Now turbos like to run on at least step 1 cooler and they love the iridium's.
