my son bought a 94 concours
it had sat awhile (not sure how long)
we got it put it in the body shop(family friend)
for 2/3 weeks picked it up ran about 3-4 hrs
then started to have problems
checked this site out
ran codes came back bad map sensor
started getting worse wouldn't even start
put in some stay bil gas treatment
some gas vapor in the intake
after some time it started and started getting better
as time went on (about an hour)
seems almost perfect now
any imput....

thanks
