I just bought my 89sc a couple weeks ago and am very pleased with it except for a few problems. my first problem is and idling problem. The car will idle perfectly fine around 900-1000 rpms for about 1 min and then the rpms will drop off to about 500 with an extremly rough idle. my second problem is with the check engine light. It comes on at random and shuts off quickly. I have pulled the codes and they are for both the o2 sensors and the maf, all of which are new. i have tried clearing the codes but they return. any advice would be greatly appreciated.
Thanks
