sounds like you got a nice deal on her . i would test the vacume lines first before paying the 300 that curt wants for the setup . you my find that it could be a ck valve a actuator , or another single piece , that might solve the problem . i rebuilt my whole system for 50. by doing it myself .if you didnt get a helms/ factory service manual with the car i would invest in one now . it sure makes trouble shooting easier . enjoy your new ride . these are amazing cars . caused me to by 2
. ps headers and upper end porting can put you in the 400 rwhp zone and then these cars get really fun
