Multiple Codes: need help with plan of action.

[levidoug]

I am new but have been reading forum for a couple of weeks.

Some history first on issues:
Recently started getting the P0300, u0100, P0700, and P0606.
Fixed the P0300, random miss fire - fixed by replacing plugs,wires and coil pack.
When replacing the plugs found oil in tubes, found the valve cover was lose and not
tight. Tighten them, check yesterday no more oil. Also the plugs(were not tight either) had oil
on threads.
Now I am getting P0606 (ECM_PCM Processor), P2105, P2106, P0700, U0100, and P0700(a second time). Runs good when it doesn't shutdown, just before it shuts down, I notice a difference gas pedal/throttle response, I was paying closer attention today. This has happened a few times over the last 3 weeks. I have a code reader, gives me a lot of information under the P0606 code. I have cleared the codes from this afternoon.
Also it seems to be worse when the weather warms up. At night when its cooler, it does not seem to shut down
so far.

Any insight or information. What should I tackle first. Clean the throttle body (drive by I think)?
Found a place on to repair ECM and the TCM or just replace.

I know this is a lot but need help much of the work so far I have done.
Always willing to learn more.

Thanks

Since I have got no response, I have kept looking. Found a small hose that goes to the
throttle body at the top to the right when facing the TB, there are two, the smaller diameter one is cracked.
It is shaped like an L. It is not the 4 way to the left. Does anyone know how to find this part?
I believe someone else replaced this part and had a hard time finding it. Trying to eliminate the small
things I find.
Thanks for any help.

Thanks avguy. I will do that plus I found cracks in the vacuum line going to the Throttle Body.
I had looked before but they didn't show up until it was getting warm outside and muggy.

Thankis

Doug, for cracked vac lines, you should just be able to repair using normal 3/32" vacuum line and splice it in. Cracked hoses usually throw a P2076/77/78 whining about the IMT valve or the idle will surge and hunt.

Thanks all for the input everyone.
