Car stalls out after replacing a lot of parts

Asked by NavyVet49 Jun 14, 2023 at 10:03 AM about the 1999 Buick Park Avenue Ultra FWD

Question type: Maintenance & Repair

I have a 1999 Buick Park Ave. ultra. I have changed out the fuel pump the fuel

filter. I have changed out the oxygen sensor I have given it a tuneup. My Car is

still running rough. I don’t have any check engine lights or codes. I adon’t have

any vacuum leaks. I changed out the TPS sensor. After changing out all these

parts I still have my car running rough and stalling out. I am going to change

out the fuel injectors but I don’t want to keep throwing parts at my car and it

still have the same problem. Can anyone give me advice on what to do?

Intake leaks ? The gasket on the 3.8 have to be changed every 80K or so . Learn to diagnose and you won't have to throw parts at it , Spray some carb cleaner down the throttle if you can .
