Quickie TB Cleaning

Tue Mar 8 09:35:28 CST 2011

I've seen this too, after as little as a week parked, and without the dead battery although that makes a lot of sense.  The culprit always looks like it's the EGR in these cases but does the IACV ever figure into a problem like this.  Me, I always suspect sensors because I always suspect things smarter than me.  :-)

I had to do the same thing when my water temp sensor (or maybe was it sender... it's so long ago now) went bad.  James McColl's mechanic/buddy was explaining to me when I was up at Shannonville
 once what the problem was.  At the time I had this problem where the car gave me trouble starting and, like you guys are describing, I had to floor it to keep the engine alive.  It got bad to the point where it would stall as I was driving it and, again, I'd
 have to floor it to start like it was carburated or something.  I explained the problem to James's mechanic/friend and he told me to swap the sensor (I'm pretty sure).  He explained that the sensor being bad fooled the engine into thinking it was -40 degrees
 or something stupid and it restricted the amount of air so you needed to open up the throttle to get more air.  It went something like that.  I doubt that's the problem Jon's having though.

To answer your question Jon, if I recall correctly ( and it makes the most sense) the smallest of the EGR tubes had the most blockage when I cleaned mine out although there wasn't much blockage overall AT ALL
 in mine and my car has had a perpetual check engine for EGR since mile 0.5 or so.  I think it was a small elbow that was about the width of a pencil between two rubber hoses and it had a little blockage but not much.  I can take a look at the car when I get
 home tonight and try to take a picture for you

I've let SR20s sit for extended periods, and just about always had

trouble getting them to start / idle. Holding the throttle wide open

often gets them firing -- which makes me think they're prone to

"flooding" but I can't think of any place in there for fuel to puddle.

And then they seem to require some driving time to "clear out" what ever

was bothering them. 
========================= 
You know, this jogged my memory. I am pretty sure I had the same issue when I installed my freshly built engine, my DET, and when we swapped my old engine into our LeMons car. Anyway, my point being that I had to do this with even a freshly built engine.
 Strange. I thought it very strange at the time - it's something you'd expect with a carbureted engine.
