Not 100 percent sure how to make a post but I have a 1993 Del sol and when I bought it, it had no issues until about 2 months in. My CEL comes on when I’m on the highway for a certain amount of time and the car goes into limp mode And the code is for the fuel system. It keeps getting worse and now all the lights come on , Cel battery and oil and the car dies randomly in the middle of the road. Im at a lose because I have replaced the fuel pump, fuel filter, catalytic converter, muffler and transmission and each time it turns on the car’s conditioning is getting worse and my mechanics have no clue what could be causing it and I’ve heard a lot of mixed things but was wondering if anyone knows what could be causing this issue. It only happens After going high speeds and it’s not a consistent. Please help
