rpm jumps down Help!
hey,
i just got my ark exhuast installed today, and i encountered a weird rpm promblem, it doesnt happen all the time, but it happens like 3-4 times a day,
the rpm jumps down 2 slits before 0, and it feels like the car is going to shut off, but it jumps right back up under 1, and this happens on Idle only!, when driving its fine, do you think its the exhuast causing the promblem? or do i need to clean my throttle bodies? its weird because it never did that before i installed the exhaust.
thanks for the help

HKS filters? the green foam stuff? Those are not meant for street daily driving filtration. Take them off now and install a proper dry type filter. Those are meant strictly for circuit racing where maximum airflow is needed and they are there simply to prevent large debris from getting sucked into turbos/engines.

they're still the same material and personally I wouldn't use them. I had a really old article wriiten that compares filter media types from different manufactureres. I don't have it any more, anyhow they HKS green foam stuff was the worst. You'd be surprised at the junk they found going through the filter. The AEM dryflow had both the best filtration as well as the best flow characteristics.

I found the test online. It was done by a Japanese magazine.
