I haven't ever done the seafoam clean before...so a bit hesitant on exactly what to do there...
Usually i just add a half pint of B-12 (into crankcase) about a hundred miles or so before an oil change...clean enough?
I am still half expecting to see some EGR codes pop up again in the near future, as i have gotten them in the past when everything was supposedly working good....Before plugging in the ECT i was getting a 327 (EVP circuit below min voltage) and 334 (EGR closed valve voltage high) Caused by the ECT? The EGR system is kind of a mystery to me.

Sorry...forgot to mention i had the battery disconnected while trying to find where the pesky connector had fallen into. So it was indeed cleared.

Forget the crankcase. 1/3 through the power brake booster Vac hose at warm idle, shut down for 15 mins, then restart & blow out the smoke. 2/3 in the gas.

There are small letters that flash on the display during Error code readings, O,C & R this denotes the type of code! O = KOEO/Active. C = Continuous Memory/Does not mean Active by itself, just previously Active R = KOER/Active. Clearing the KAM (keep alive memory or kept adaptive memory)has nothing to do w/ the Continuous memory, other than it clears it also. koeo/ O = key on, engine off. koer/ R = key on engine running. C = Continuous memory. They relate to how the codes are interpreted. #33C is interpreted differently than #33R

My time is limited during the weekdays...but i managed to squeeze in a KOEO self test today after getting home from work. The 327 O and 334 O are back again. Plugging in the temp sensor did not save me a lick of fuel. Estimating 10 mpg...will know closer tomorrow or wednesday the actual mileage. Will also try to get in a engine running test now that some codes are popping back up. Any ideas now as to why my mileage may be crap? (Besides the obvious...plugs/wires/air filter)
Not sure why...but I have this idea of "lazy" weak injector/s, but sadly no fuel pressure gauge to check if they are leaking down prematurely.
Also picked up a can of seafoam to smoke out the neighbors in the next day or so as well.

Hi-Rev Motorsports
weak spark and lack of timing....
do a full tune up with a new coil and bump the timing then go from there...
too hard to trouble shoot issues with a mass amount of variables....take as many out of the equation as you can...also clean the injectors...

Sounds like your EVP sensor's bad too. I would remove, clean the EGR Valve & inspect its diaphram also. As long as your cleaning stuff, do the IAC. Agreed, remove variables & you have many.

Alright...thanks for the suggestions.
I should input some more info...
Six months ago i changed plugs.wires..cap and rotor...no coil tho....two months ago i cleaned the IAC hoping then to improve mileage. As well i gave the K&N a good soak before oilin it back up and reinstalling.
A couple weeks back i dumped in some lucas injector cleaner. Last week a can of B-12. Injectors should be clean.
Tonight i ran the full test...KOEO getting a 111 and then a 332 and 334 stored in the continuous.
On to the KOER i got a 327..332...and 334...the 332 is a new one at least since i cleared a few days ago.
332 is insufficient EGR flow. So i pulled the hose to the canister on the fenderwell just checking flow there...seems good.
Pulled the neg, to reset codes and ran the KOER test again. This time i got a 412 and 332. 412 is cannot control engine RPM during KOER high RPM check.
So that leaves me wondering what to do next.
Coil i will replace this coming weekend.
Obviously my EGR needs some work. But as i said earlier...the EGR is a bit of a mystery to me and i don't exactly know what to do with it.
The 412 code...i guess i will "ignore" for the time being, unless someone has an idea.
Now sorry for the long post and hopefully someone can help me out...
Oh and i performed my first ever Seafoam job tonight as well. I thought it was a bit lack-luster, maybe i shoulda let it set in the driveway for the full effect.
