ok so i replaced my rotor and now my car is throwing a cel light. code 8 which is a tdc position sensor. i have no idea what sensor this is, i know it is in the distributor itself but dont know which part. how do i go about fixing this. a friend of mine told me most likely it just needs to be re timed and the ecu reset, that if i had a bad sensor the car wouldn't run. the car fires up but after about 30 seconds the cel lights up. i can drive it but i dont know if its safe or not. anyone had this problem and got it fixed?? i have an 89 lx. its the gay ass dpfi. i was contemplating just doing an mpfi swap but if i do that i still wanna get this fixed so i can sell my distributor. any help would be great. i have a pic of the dist. if anyone can point out what the tdc sensor is
