Timing question.

[IHateHacks]

Before you do anything drastic, did you jumper the terminals before you hooked that timing light up? Or did you just hook a timing light up while it was revving at 2000rpm?

The ECU advances the timing as much as 30-40 degrees BTDC depending on load, rpm, throttle position.

You might have been reading that IF you didn't jumper the terminals in the diag box.

And if you did jumper the terminals, that means you have no codes, correct?

Jumpering those terminals in the diag box is JUST LIKE disconnecting the vacuum line and pluging it on an old school vacuum advance distributor. <----- IF there are no codes.

And whoa there buddy, timing belt tensioner? WTF? Just take the upper timing belt cover off and see if the marks still line up when the crank is at 0.

It's called setting base ignition timing. If you did all of this, nevermind my rambling, I will promptly delete this post.
