Ive been through the VFAQ a couple of times, including some pretty nice videos online about setting base timing. I have some questions based on things I see.
The idle is erratic, and i've already validated that the biss screw, vaccum lines, the ISC, and FIAV are properly functional.
I've set the base rpm to 750rpm at the biss, once i grounded the timing plug.
Then I hooked up a timing light to cylinder 1 wire, and checked the timing marks at the cam.. they were lined up.
HOWEVER, the timing mark on pulley against the cover is lined up to TDC and NOT 5 degrees before TDC. Which makes me think that that when the timing belt was put on the timing was incorrectly set?
The car does fire up and run and all, but has a unusual behavior of dying when dropping in RPM. I've had this sort of issue in the past on another car with bad timing as this is what is leading me down this path.
In order to set the timing, can I safely pull the necessarily pulleys off and reset the timing and loosening up the tension bearing, and re-adjust or is the timing mark on the crank pulley a red-herring?
Thanks for your assistance on this.
