Back on Street

Finally.

VTEC is back.

But

Dealing with random sluggish performance:

No CEL.

VTEC still kicks in.

Ignition timing tuned with timing light.

Hardly feel sluggish before warm up, usually happens after warm up.

Lost of torque in sudden.

Weird grinding sound during 2k ~ 2.5k rpm (Hardly happens).

Unstable power output through whole rpm.

Sometimes the sluggish just go away and drive like normal.

It just happens randomly and it last quite some time.

SOLVED: Changed Distributor

But the weird grinding sound / rattling during 2k ~ 2.5k rpm still happens...but rarely.
