Codes after new headgasket. Water pump.

update found the purge sensor disconnected. plugged in got 34 mpg in traffic today. normally 38-40 on 70 degree days.
i don't think its 1 tooth off. i listened here thinking it was a head gasket with a cheap bad borescope..the pistons looked night and day all good.
i get the rumble when it starts 40% of the time. and on taking off till 30 mph. if i floor the car it goes fast.
in the past a clean egr cooler fixed this. runs just a little worst before much better.
in the suburbs. the car gets 40 mpg to 50 mpg. before new gasket.
i also had Rumble with a bad hybrid battery. could I have a bad injector.?? thanks in advance

 

Seems like all is connected proper. 2 things.
Should I spray the manifold with soapy water to see if I got a leak.?
And the fuel injectors were very grimy on the exterior. Is it possible while I removed they and spray cleaned them. I got 1 more cloged?
At this point besides timing chain. I don't know what to look for. Overall the car don't run horrible.
Just the rumble when starting. But like this am after sitting.it may not rumble over night . But will thur out the day. During fuel acceleration. At fuel power it's good.
Upon checking the timing marks. Other guy here says on crank you can see the marks ??
Explain how.
I have no problem removal of covers to check. I just think it's something simple.
No more codes . Had a engine power code and cly 1 code. All are gone now.
not just in historical. But regular code.
Evap Code is only code left in history only. All codes are gone. No check engine 100+miles driven in city 50.

 

Tks.
