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.

 

Coming to think after checking everything. Car has power. Rumble during take off. Cones and goes. Same as idle. Great than just ok.
Mpg today normally 38 -40 at 60 degrees out 32 mpg. Wife's birthday is tommorow 51..
Thinking you may be correct. The head gasket is not so hard like all say. Like a puzzle alot of steps only.
If I would install the chain again. I would put maybe grease on crank to hold chain. Or a baby string that won't hurt the engine. Tie the chain to the crank only...

 

When looking at the crank. How do I tell if it's lined up to the chain. In the picture . Thanks for the picture.

 

Thanks for your answers. Let me clear up a few things. All oem parts.
No big carbon anywhere on disable.
Big carbon on intake and egr cooler many months ago.
It's not pinging. 62 years old. Old guy here
Seemed before I brought the battery it was worst.. got alot better with the h.v
Battery .
Before I took it all apart . It had the rumble very little. Just loss of coolant.
I am no descriptive proper about the description. First off all codes are gone.
Seems to me you are correct with the timing change. As it's best described as a misfire and start and low speeds mpg 32. 2 weeks ago 40 +
If the bottom timing mark on the crank lines up. But the cams are off. Remove the cover and reset the timing gears.
I strongly believe that this makes sense as the crank gear on the chain could easily move. During install...

 

Think it's best. Just to pull the cover off and look closely. It's not that hard. Take a couple hours complete?

 

Ok t.y. if they are incorrect. Must remove the cover to fix if it's off alittle. 1 or 2 links..I will do as you explained on sunday.. say wife's birthday. If they look incorrect. I will remove the cover and repeat the setup.

 

Tks. Will do.

 

Thank you for all the great info you post for us..it's super value..
