I've been having some misfire issues so I've installed the HKS DLI ignition. The install was very straightforward and the engine runs much smoother now. However, since installing it, the idle is very high. Normally, idle was somewhere around 8-900 but now it is around 2k. Even after warming up and driving around for about 10 minutes in 80 degree weather, it still idles high. Anyone else had a similar experience?
