1999 ES300 Hesitates and Loses Power
I'm new to posting on this forum but have been reading the threads for about a week now. Definitely am happy I found this Lexus family.
Got some readings from AutoZone and Advanced Auto Parts:
Codes - P1354, PO446, PO420 Bank 1, PO330 Bank 2
Work Done:
1) Husband replaced spark plugs
2) PO330 - both knock sensors were replaced, along with Intake manifold gasket & hose
Car still hesitating and losing power, most notably at speeds over 20-30 mph. It bucks like a horse; almost feels like something is blocking the fuel (if that makes sense).
Took it again to Advanced Auto Parts for code reading. This time, only code that came up was "Enhanced DTC", a dealership code.
Not sure where to go and what to do next.
Any suggestions?
