This vehicle is not the one in my profile, this vehicle is a 1990 Talon Tsi Turbo FWD completely stock setup.
Here's the situation:
Initially when I got the car, it would intermittantly run really rich and choke out. Other times it would run so-so. I replaced the plugs, plug wires, battery, and o2 sensor and still the same symptoms. I made sure I had spark in all the cylinders and then tested the fuel pressure. The pressure reads really high, something like 55psi on average when I put the fuel pressure tester on the return nipple on the fpr. That would make sense then that it runs rich obviously. I figured I had a problem with my fuel return line so I cleaned that out and made sure it was flowing well. Still no fix. I checked my fuel pump, it has juice and works well. I replaced my fuel pump relay, and my fuel pressure regulator. I also put a new MAFS in. Still no fix.
Any suggestions or ideas are great thanks in advance.
