Will This Damage My Engine? -- Heads/Cam Install
Hi,
Had heads/cam and LSX intake installed in September. Power is great and the idle is fine (was increased to 900). My problem is that when I am coming to a stop and depress the clutch my RPM's drop down to about 500 and the engine hesitates a little and maybe one second later the RPM's jump back to the 900 mark. The car has yet to stall on me, but I am concerned that over time this might harm the engine.
Is this something that can be cured with an LS1 Edit tune?
Or.....
Is this normal behavior for a heads/cam car?
Thanks,
Matt

Definitely sounds like a tuning issue. I've been doing a lot of research on cam's, and idle is one of the areas affected when going to a bigger cam, especially in a A4.
I would have the shop plug LS1 Edit to check out the specs!!!

Had it replaced and no more funky surges after coming to a stop light.
