Help Wasn't sure where to post this so I put it in two places - - driving me nuts!!
No one knows - - help.
Have an 05, C6 and it has had headers, Vararam and a tune since 1100 miles.
Developed a high speed burble, not a miss but almost like one and you could feel it: put in new plugs, proper spark plug wires, checked injectors- same thing.
Our dealer is really poor: gave me a VDR and we did see the MAF drop from over 10,000 to about 4800 in a matter of 200 rpm.
Put on a new MAF: same thing. I had a new T-body (OEM) and tried that, same thing. Tried tightening the intake bolts and they may have been one or two flats loose: same thing.
Dealer says you have headers and ram air and we can't help you: told them it has been fine for 19,000 miles so it wasn't that - - any ideas out there as to what is causing this burble at about 6200? (REv limiter is set to 6800 - - it isn't that).
If you think you know all ideas are welcome - - Thanks
John
