Previously I experience a CEL code P0171...I tried to find the possible causes but still no luck so far. Already performed a tune up about 30,000 miles ago; I'm currently experiencing LAG every time I step on the gas, Some times when i take off quick it feels like the clutch is sleeping (difficult to explain, will probably upload a video sometime).
So, the question is, what do you subie noob and experts think I should do to get this hesitation gone? I'm thinking of replacing my plugs (I don't know much and I'm still on the learning process (noob)), do you suggest replacing my Ignition coil too? those babies cost some serious money BTW!.
Your suggestion is greatly appreciated.
