Stumble under partial/ full load in wet weather only.

[PunkST]

Its been rainy and humid the past few days in wisconsin/ illinois. And upon driving home from my girlfriends place my car is doing what it did last year. After a short time drivinf in the rain i get a stumble when i go to put any form of load on the engine. Doesnt matter gear or rpm. Its like its blowing the spark out.

I thought last year it was my step colder plugs. Put fresh stock heat range in late summer. And its taken till now for enough rain to bring the issue back around. Its not a traction control intervention. As there is no wheelspin. Just lack of power and not much acceleration. Warm dry weather the car acts completely normal.

Any codes set?

 

[PunkST]

All i still have is my p0456 and p219A for the cracked evap canister. But this was going on last year with no codes being tripped before i cracked the canister this winter. Its one of several large aggrivations with this car.

Just for Poops check emission fuse #24 in the fuse block under the hood.

 

[PunkST]

Ok.

My next step would be to check for corrosion under and around the battery cables as this has been a weird phenomenon. As water and electricity don't mix..... with corrosion thrown in the mix. Not good bed fellow.

 

[PunkST]

Its fine. And my fuse box is totally dry. Whole underhood area seems dry to the touch.

 

[PunkST]

No corrosion of any serious level on the terminals.
Im soooo sick of sinking money into this car this year. And im still waiting for the replacement evap canister.

 

[TyphoonFiST]

Its fine. And my fuse box is totally dry. Whole underhood area seems dry to the touch.

The reason why I ask is I had that fuse blow and had the same symptoms.

Im starting to think my car is just a giant piece of crap. Its charm is totally lost on me

Don't give up we can fix this!

 

[PunkST]

Some have said my MAP intercooler is too big and gathers water inside when its humid. I call bullshit because its a factory fit piece. And i know my charge pipes are all tight. No holes in anything. Still the same tune. And no change when flashed back to stock tune last year. Its so damn strange.

What's mileage of the FiST?

 

[PunkST]

84k. Been doing this since 56k every time its warm and rains. Cold rain, no issues.

I have a Gen2 GTX2860 on my FiST....When I blow charge hoses....Its gutless.....Possible boost hose leak? Do you still have the Sound Symposer hooked up?

 

[PunkST]

No symposer. Cpe charge pipe wont allow it. No leak, it made/ makes 21-23 psi without a problem early in the drive.

 

[TyphoonFiST]

Factory boost hoses?

 

[PunkST]

Nope. Full cpe charge pipes. And everything was double checked a couple weeks ago when i adjusted the piping to keep from rubbing on stuff.

 

[TyphoonFiST]

Not pipes.... Hoses silly!

When are you expecting the Evap. canister?
