Easy fix if > that's the problem. i verified this about 3 weeks ago when i had to do emissions again. it was good, ~14.4v at 2500rpm. when i bought the car it was at 30psi with about 23 mpg. it got about 9% co at the etc, then i took it to the shop (porsche) as a last resort, they took the pressure down to 23psi, yeilding 5% co at etc. i don't think it is realy that much since we are looking at %'s -- nathan http://www.orntar.net/project/vwt3.html 1970 fastback ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
