I have searched and searched and haven't found a thread on here with the same symptoms as I am having. I was cruising down the interstate a while back at about 100Mph wasn't pushing any harder, just a steady cruise for a few miles on open Highway.
As I was approaching my exit got hit with a blinking CeL and car felt like its been running on 3-cylinders(could be wrong). It starts up every time, starts right up, aside from a slightly long crank occasionally.
I read the codes and it is giving me 3.
First code was 1 2-direct power input to the PCM has been disconnected within the last 50 key-on cycles.
Second was 4 3(which throws various codes) but an Obd2 that I read on it read a bouncing misfire, sometimes would say 1 and was reading as 2 other times.
and the last code was 3 1-Evaporative purge solenoid / Clogged purge line / Vacuum hose / Evaporative emission canister clogged.
The car isn't running too too terrible. Mostly steady idle about where it should be...acts like it wants to die down sometimes though but catches itself. Seems like it wants to hold back a little bit but not bogging down too hard or anything. I have changed coils, plugs, and wires, and tested catylytic converter and the car has yet to improve. I know I Need compression test but in the meantime, was wondering if anybody has had a similar issue. I'm planning on changing upstream 02 sensor next, but was wondering if anybody has any input?
