General Topics / Funky AFR hump, any help
« on: February 02, 2009, 08:14:57 PM »
Hey guys,
new to the forum... Dyno'd my car the other day and there is a strange hump at 4K it goes lean and comes back to normal after about 500 - 700 RPM's... It is completely stock... I have check everything and so has my local mechanic and can't find ANY leaks...
Is this typical of the engine? its consistent and EXACTLY the same EVERY time.
any help would be appreciated.
