Hi Guys, been working hard on my GLHT for summer. Replaced head gasket, new tu60 turbo, deleted egr and got custom elbow made,
spearco T1 intercooler setup. Installed wideband about 28" from turbo, at idle the wideband starts at 14.7 and then consistently
keeps dropping and after about 3 minutes as the engine warms and idle lowers it reads 10 on the wideband. Using stock injectors .
Changed FPR with same results. Car has an MP logic module. I'm worried im washing the cylinders with fuel at idle. Any Ideas?
My other concern is I get a consistent code 23 for the air charge sensor, replaced it, changed the pigtail and wiring and it goes away and
then comes on again. Any ideas on this? Thanks for your help.
