car wont run right with correct ignition timing

[tsidrift1]

Here's the deal, i have a 92 tsi,(mods listed in my profile). I have tried to set the ignition timing. When i set it at 5 BTDC, it runs like crap, but it idles well. I noticed that it runs a little better if I advance it a little. When I advance the timing, the idle gets horrible. I have been tryin to figure out why the car jumps the timing light on the gun. It has some misfire in the idle and while driving, everything in the ignition has been replaced with a new or used part. I was told from Oldmitsutech that it might be my cam sensor. I told him that the light on the gun wont flash at a steady rate, every once in awhile it will skip a flash. Could the cam sensor really be the culprit of this misfire at idle, making the car feel like its being held back while driving, and jumping the timing light like I had explained earlier.

Let me know guys,
Anthony

Did you ground out the timing adjustment connector?

That connector has to be shorted to ground, and if you have a datalogger, you must unplug it from the diagnostic port before you adjust the timing. If you don't ground it out, the ecu will continue to adjust timing while you fiddle with the CAS.

i know thw connector is grounded out. I have a logger cable that i made and I have left that plugged in, if that would make a difference.

No, you got it reversed. When adjusting timing, the logger cable must be removed, only the terminal shown above should be grounded. When performing a BISS adjustment, both the above terminal and the diagnostic port have to be grounded.

OK, I will try that when I get home and see if that does anything.

Yeah, I worded it wrong. Ground the timing adj. connector, unplug the cable from the diag. port.
