2010 EGR Cleaning then cold engine shake

Hey guys. Hope you can help me figure this one out.
2010 135,000mi. Last year I luckily ran across info here on an extended warrantee EGR valve fix. Engine shook on 2-3day cold starts and burnt oil. They replaced EGR valve and that is it. Engine slowed on the oil burning. Last week at 139,000 mi went in and pulled the plugs and did a piston soak as I cleaned EGR, EGR cooler and pipe, then replaced spark plugs, PCV valve and added Catch-Can, coolant and tranny fluid replacement. Had all kinds of flashing warnings on instrument panel when I started her up but eventually all evened out and only check engine light stayed on. It disappeared after a couple starts.
Drove about 150 miles, runs real good. Let car sit for a day and engine shook bout 10 sec. on the cold start. Drove, runs good. Shut off engine and unplugged EGR and started up. Run good. Check engine light returned. Went to O'Reillys and they read P0403, P3190, P0102, and P0113 codes. All cleared but P0403 code. My guess is EGR valve but it is only 1 year old. I cleaned it what little it needed. It opened easy. On overnight cold start engine seems to shake a little before it clears but not as bad as a day or so of sitting. Any ideas? Thanks

 

OMG didn't realize intake cleaning was so critical. Sure would have made replacing PCV valve easier if I'd a known. OK, I'll dig into it again but I don't understand why the cold start shaking after I cleaned everything else. It was not doing that before I cleaned the cooler and pipe. Appreciate your help guys. Thank you.

 

Truly appreciate the knowledge and advice, Leisk, Bisco, Grit, and Merkey. I'll get some cleaner and brushes, a gasket, and go to town. Unfortunately, the only place I have to work on it is my brother-in-law's bout 100 miles north so I'll head up there in a couple days. I'll let you all know how it goes. Thanks again.

 

If you read previous post you see that I replaced spark plugs, adding oil catch can, cleaned EGR system that had a new valve already, then after solid advice because of engine shake on start up, I went back and thoroughly cleaned intake manifold which was filthy. I might add here that a 12 guage and 22 caliber gun cleaning brushes work great for cleaning the manifold. My problem, car runs great and my mpg is up but the bugger still seems to want to stutter very briefly on start up. It is just the very first "hit" or two of the engine start. It isn't smooth, you can feel it is a little rough...just at the begining of the start cycle, kinda like a stutter-step. Yesterday I started it then shut it off and restarted. Did this 3 or 4 times. All starts seemed to me to have that little stutter and one time more than just a little stutter on the start.
What led me to do that sequence was that I suspect the culprit to be the oil catch can since there is so much more hose space involved in the installation. I thought maybe the catch-can hose takes so much more filling of vapor to get to manifold maybe that was causing the stutter. but by restarted right away the hoses were already full. Now I don't believe the problem is in that as I also haven't run across any posts with problems after the catch-can installation. My only other guess is the valve, but it is only bout a year old and I cleaned it the little it needed and it moved easily.
After I cleaned the manifold I got rid of the common P401..(?) code. So as far as I know it isn't showing a code. Appreciate any feedback. Getting ready for a long trip out west and this is bothering me. I'll be camping in some remote places and sure as heck don't want to get stuck somewhere with a dead Prius.

 

Thanks for the reply. Yes, previous post is on page 4 as it was posted awhile ago. Engine doesn't miss, just seems to start a little rough in first couple of engine revs otherwise it runs good. Haven't noticed any radiator coolant level change. I regularly use a good quality top engine cleaner. But I am going to put a can in the tank as you recommend. I travel quite a bit so I don't believe it's the fuel. Engine runs good, 140,000 miles, hot or cold .I don't notice any difference between cold and hot starts.

 

I'll do the injector cleaner, thanks. Yes, Leisk, I cleaned the throttle body. My intake manifold was filthy. You did me good.
I may have found my problem. Tore the engine skid plate off and let it run so I could maybe hear a leak or see something weird and I did. I saw that the 3/4 heater hose I used to go into the intake manifold from the oil catch-can was collapsing. I only had about 6 inches of the 3/4" from the intake manifold and the rest was reduced to 1/2" back to oil catch-can. I don't know if this was the problem as the hose wasn't completely collapsed but it sure was restricting the flow. So I cut a piece of 1/2 " hose greased it and stuck it in the 3/4 to stiffen it up I didn't have any copper. I'm not entirely sure the fix will solve my issue but it does seem to start a little "easier". Or it may be wishful thinking on my part. I'll have to drive it a while before I know for sure.
I also took the EGR valve cover plate off and made sure it opened and closed easily, no problems there. Appreciate everyone's help.
