my ti does not like cold weather?

[jordanmc]

Let me preface this by telling you that in this part of SoCal we see about 20 days of cold+rain a year.
That leaves 300+ days a year of beating sunshine and humidity under 20%.

Yesterday was the first time in 6months+ that I did not drive my car or even start it.

Yesterday also happened to be the first day in about 8 months that it rained.

Today was the coldest day that we have seen in about 8 months also.
(it was so cold that I had to wear a sweater out during the day, and I had to start a fire at about 3pm cause it was so damn cold(thats like below 50))

Tonight when I went to start my car it chugged a bit and then died, 3 or 4 times, throwing the CEL

It acted just like my sisters 74 karmann ghia every morning, where you need to give it some gas for 25-30sec before you haul ass down the driveway to build a little heat.
Once it got warm it was fine.

The engine is in great condition, but after reading other posts about dying engines, im sure that the spark plugs, icu, tb and fuel filter need cleaning or changing, which i will be doing before the end of the year.

Any tips from you cold weather ppl I should know about?

mine used to do that, the intake boot was cracked and when it got cold the rubber would contract, making the hole bigger, have you checked your intake boot?

[elchicano]

yeah i would check the boot. I had that happen to me a couple of times. I didn't know what it was found out later it could of been the boot. I changed it and when i bent the boot a little there was a big tear along the bottoem of it.

[jordanmc]

by intake boot do you mean this?


or the thing that sticks out toward the front of the car that is attached to the box i have circled?

What did the CEL say? I'm thinking it may be a temp sensor of some sort. Air intake or coolant temp.

I've started my ti down as low as -30F, so it'll run fine if all is well.

it's the rubber boot that goes from the throttle body to the MAF, the part you circled is the airbox

the CEL came on when it died along with the battery light, but shut off when I tried to restart it.

It was a little warmer today, and i started it long after the rains had left.
It chugged a bit, then was fine when I gave it a little gas

Is this the boot?


if it is the part, then it is totally starting to wear, in fact, it was the only piece on the engine that looked a little warn when I got the car.

as long as it is not raining, ill be ripping apart the whole air intake system

my goal is to get down as far as the icv ( or whatever that part is called that is under the manifold)

I doubt I will get that far, but I will at least give the maf a good clean
hopefully that will help

I cant find any cracks in the boot, so i will continue with the general tune up, plugs, etc (all that **** pumping air into my engine)

ill let you know how it goes

[jordanmc]

ok, i finally had a little time to take a look at this

no cracks in the boot, I gave it a good clean as I inspected it as I know it has never been changed. To my shock the thing is in great condition.
I did notice that the piece connecting it to the ICV was sticking out about half an inch, I pushed it back in, and it sat fine. Im thinking that was the problem


I also found a very tiny crack on the actual hose going to the ICV


it is very small, so Im just going to replace both those connections when I have the whole upper manifold off this weekend

Thanks for the tips guys!!!
