Engine Performance problem
Buick Park Avenue 6 cyl Front Wheel Drive Automatic 72000 miles
Engine stalls/stumbles when cold, fine after 5 minutes. Replaced o2 before cat, for 13 and 44 soft code that was loged, replaced air cleaner temp sensor, replaced TPS per repair guide recommendation, . Replaced dirty air filter. No fix
I can hear egr actuator sounds during stumble. Is this the problem or is MAF at fault. Can fuel filter be cause. Need egr test procedure/ fuel pump pressure specs. Maf sensor test procedure. Need solid fix or trouble shooting help. On fixed income. Can't afford to replace good parts.
have the same problem?
