I suspect that for some reason the FI is running way too rich. 105 psi is not too low for a low compression 73, which is what she has. I would check to make sure that each cylinder is actually igniting by pulling each dist cap wire off in turn. Check the plugs, valve lash, timing, and advance mechanisms also. Then check the charging system regulating voltage. You should measure over 13.5 V at the battery after a drive and at med RPM. Let us know what you find. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Search old messages on the Web!
