So the P0069 is back again with new "symptom" echo engine revving.

the idle is unstable now if you tap on the gas the engine will have 3 addional echo engine revs...


so say if you revv the engine to 800 rpm it will go down to 590 then revv back to 800 then back to 590 then to 800rpm then settle at 590-620rpm......i would really like to fix this "issue"... i have a trip pretty soon this month

honestly i think the engine is toast :( it sounds horrible on #3 and #5 cylinder(slightly worse then #3) #1 and #7 cylinder sound fine..



i'm going to clean up the ground wires and a adjustment to the map sensor as well as check the air filter maybe it sucked up some snow ?

Why do people still post with no vehicle info? Am I just expecting too much?

I look forward to searching for info to try and help without, 1. Not knowing about what you just said about info all over and 2. Having to search when the info could easily be in a signature or supplied with the post so I don't have to go looking for that info.

So, in a nutshell, I did get the answer to my second question, I am expecting too much. I will file that away in the "who cares" department. LOL!

I don't need the whole history unless the current problem needs that history for it to make sense. I was only asking for year and engine size. I thought that was pretty easy.
