Is this the same canister "boiler" mentioned a week ago in this thread that everyone just ignored??

Seems a good theory that could be easily tested by removing the fuel cap once the problem presents itself. This would release the vacuum until the fuel level dropped off again.

 

I believe so. I just got the service center to check the service records to double check what was done and they just have "replaced charcoal canister" listed.

 

Very interesting topic. The same is happening to me, mine is my00 gp white. I have no idea what is causing it. Ive owned mine for 6 months now, and it has gradually gotten worse to wear this happens everyday. Ive tried map whackin and map beatin, nothing will work. Ive tried resetting the ECU, notta. When I map whacked, it seemed like it fixed it for 2 minutes then back to the same thing. My car will even idle funny when this is going on, almost cutting off everything and shutting my car down. I use Chevron 93 octane everytime, with exception of the 87 octane my father put in it the first month i owned it. Since then I have ran the gas down to like one bar to ensure it is out, then refill wiht the good shat. WE NEED HELP.

 

Hey Lycean, that sounds like it makes sense. How much was the part to get fixed, and where abouts is it located on the car, I have noticed a noise coming from where it seems like right around where the doors are (halfway or so back). Let me know or PM me or something, very interesting.

 

You've got trash in your fuel line.

 

Something else I would like to add to my problem, I'm not sure if its his problem too, but I think its related. Its a slight backfire buildup when low rpms are in. Like, when I'm idiling at a roll, or slightly gassing it before 3k rpms or so, I can hear like a gurgeling of gases, almost as if its a bigger engine....I know that sounds quite stupid, but thats what it sounds like, and then eventually, if i keep at it, it will just backfire a little bit. I'm not talking about "KKKAAAAPPPOOOOWWW" like your grandfathers 81 custom delux, just a small "cough..cough". Any more ideas? Thank you all for the great input

 

Yes, we're talking about the same part.

 

What do you call cold? I've found the problem to be not as bad in winter but if
I'm stuck in traffic long enough it will still happen. I may have an extreme case because I hit bumper to bumper traffice at the end of a 100 zone.

At least try the radiator mat before outlaying more money on components and see if it makes any difference.

 

I think the charcoal canister makes sense. I'll call my mechanic tomorrow and ask him how much would it cost to change it, i'll write again to you guys, really thanks for the posts.
Lukep6470 mentioned radiator mat, what does this mean? (sorry for my english, it's my 2nd language) ?

 

PS yes i do have a lot of pressure in the fuel tank, when i open the cap to refill it, the pressure gets released.
