High idle/engine bay temp when it's hot out
High idle/engine bay temp when it's hot out
Sometimes when it's hot out, after driving the car around (usually city driving), when I put it in neutral, it idles really high (between 2000 and 3000). When this happens, the engine bay is usually pretty hot, like to the point where my CAI is sometimes hot to the touch. Also, if I give the gas pedal a quick tap, it'll rev up and then return back to a normal idle.
It did this with the stock K8, and now it does the same thing with the KLDE.
Any ideas?
Oh and if it makes a difference, engine was completely stock before, and now I have a DE, using the K8 intake manifold, VAF, and ECU.

Put in Phenolic spacers. I have an extra set. If you don't know what they are, check the "search".

Check your TPS, make sure its set correctly and also the idle screw on the TB.

is this a common problem? I did a bit of searching, but didn't really find anything

Re: High idle/engine bay temp when it's hot out
Yeah, sometimes the search is tricky.
It's very common. When I would drive accross the desert, my IM would get so hot that the car would bog badly, since the little car has the V6 stuffed into it. You could also wrap your exhaust manifolds. The spacers make a big difference. You can actually touch your IM after a long hot drive. I also bypassed the coolant lines that go into the TB (IAC). That helps a little, too, but your idle isn't steady. I heard recently that you can turn on your defroster, and it smooths out the idle, in this case. Also, I took out all the insulation, and weather stripping under the hood, for better airflow.
What really worked was when I rerouted the window squirter line to spray the IM with distilled water, through 9 mist nozzles.

(Be carefull on the electric parts)
the_anj: Sound like typical idle issues. Follow TPS and IAC adjustments That must be tricky to tune a K8's IM on a DE

Re: High idle/engine bay temp when it's hot out
Not at all, zzzoomx3 and i have this same prob. We haven't been able to figure it out but I noticed that my acc. cable has a lot of play whenever it gets hot. I will let you know as soon as i figure out a solution.MX3ak wrote:HEY That's the coolest mod I've ever heard!!

What's the chance of you tracing the outline of those phenolic spacers so I can make my own? Is it the brown phenolic?

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: High idle/engine bay temp when it's hot out
It's black, and they're about .5" thick. I can trace them for you. Mooneggs is comparing them to his ZE ones, then he'll let me know if he wants them. If not, they're yours, Anj.

Re: High idle/engine bay temp when it's hot out
Are these the bushings that you are talking about?
