hello, I have a 1993
3.4 camaro recently the fuel pump went out in my car, have since replaced and the car was running great. As I was driving home the car would not go over 35 mph when I would try to step on the car the rpms would jump but the speed would not increase . when I first started the car the oil pressure was as 80psi and when the car would shift oil pressure would drop. got the car to a parking lot and as soon as I came to a complete stop the oil pressure completely drop and the car lost power. have replaced the oil pressure sending unit . oil psi is back now but the car still has almost no power to the had peddle and when you start the car there is a semi loud popping/ knocking noise coming from the motor.

 

sounds like you spun a rod or main bearing.

 

at this point you may want to bring it to someone an hope that its not ,
