Car stalls out after replacing a lot of parts
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?
