fault code...p0174

[llll1l1ll]

Chances are, you've been driving with the problem longer than you think. I heard the whistling from my intake boot for two months until the SES light came on.

I'll tell ya hwhut, that lower intake boot is the biggest PITA ever.

I'll go into further detail later. But I attempted to take the lower boot out and clean the ICV. It was the worst thing I have ever attempted to fix on my car. I gave up when I got to the lower boot.

Yep-- the upside down hose clamp can be a real PITA. 1/4 inch socket with a swivel head got it for me.

I got codes 0171 and 1074 right after I got my car. I had a torn lower intake boot. Man that thing was horrible to take out! Definitely worth going to get some weird 6mm or 1/4" wrenches for the clamps.

I replaced mine, and reset the code. So far so good after a few days of driving no light is back. I have a small leak in my VCG, but hopefully the boot was the only thing causing the code.

Oh yeah, if you go and get the intake boots, you might as well get a spare "F" connector - the one that comes out of the upper intake boot. The hoses were basically welded onto mine and the little plastic bit on the F broke off. Needed an extra trip to the dealer cause of that stupid thing.

Just threw a P0174 and P0171 while I was on the the freeway and stopped at Autozone on the way home. I'll start by cleaning the MAF and then if that doesn't clear it I will move on to the upper and lower intake boots. Thanks guys.

Sounds good. While the boots are out, clean your icv, and inspect your disa.

When you put the boots back on, make sure that lower boot is nice and tight on the throttle body. I made that mistake.

How about this guy Kayger? Sounds like this can be a real joke to get out, I want to make sure I've got what I need for the job when I start, not when I get 90 minutes into it. Ha ha.

If you have new lower boot...just cut old one off....which opens up all kinds of room. I will not do this job...even for inspection, without new boot/s.

A small offset boxed wrench is my tool of choice, with a flex drive.

Dane, do you have a photo of the tools you like to use posted here somewhere? Is this clamp on the lower intake boot fastened/loosened with a flathead screwdriver?
