P0420 CEL - hard starting when hot - have Live data
I've been getting the P0420 CEL pretty regularly,and I have a hard start issue after engine is hot, I got some live data when the symptom has occurred.
Symptom primarily is hard starting when engine is up to operating temperature, and engine has been shut off for more than 20 minutes. The hard starting is independent of the CEL.The car starts just fine when cold.After about a one minute warm up, I drive off. The car is a little hesitant under acceleration until it gets a couple of miles of highway driving. Once it is up to full operating temp, and I stop the engine, it will restart immediately after shutdown with no issue. But wait about 20 minutes and try to restart, it will start and idle fine for about two seconds, then idle drops below 500 rpm, and is a rough idle. If I try to give it a little gas, it burbles and runs worse, then will eventually die. Subsequent restart attempts fail. After several attempts, it will finally start and run fine. If I don't give it any gas, then t idles very slow and rough for about 30 seconds, then most of the time the idle slowly creeps back up to about 700 rpm and then runs fine.
I've done this much to the car: Smoked out and fixed a vacuum leak (bank 2 cam cover), removed and replaced all intake system gaskets, rubber intake snorkels and re-torqued manifold, replaced two MAF sensors (second one is a Denso) replaced PCV valve, replaced fuel filter, spark plugs, coil packs, and fuel injectors (all previous work), cleaned throttle body, replaced IAC valve and throttle position sensor. I am reasonable sure I don't have any vacuum leaks.
I've recorded some live data when the rough idle was occurring, and after it ran fine, for comparison. I've noticed differences in fuel trim in Bank 1, and in the voltages from the backmost o2 sensor. It may be a too lean condition for bank 1 for that short period of time. I appreciate any thoughts you may have.
