i have totally rebuilt the engine in my 89 sc that i got in parts with the help i received from you very patient and understanding sccoa members now that is out of the way.i have recently intalled the engine and it runs like crap the engine will start eventually than run really rough at a minimum of 1000 rpm only with the throttle partialy open manualy, it is over fueling big time!!!! i can smell tons of unburnt fossil fuels from the exhaust. and i can hear afterfire in the exhaust pipes also here is a list of what tests and corrective actions i have tried.
checked for obvious vacum leaks .used t bird 88s intercooler gasket set.
new h2o sensors installed.
fuel pressure checked@42 psi at 1000 rpm.
totally stock rebuild no mods.
no obvious signs of damage on mass air.
engine was running great at the time a head gasket went south .sat for approx a year before the new mill.
any ideas on what i may have screwed up!!!!
thnx guys
