VE troubles
Lately i noticed my ve runs crappy when it has just rained or moist/dew and the car is warming up. Once it is warmed up it runs like a champ.
symptoms:
rough idle
backfiring
stuttering
burnt fart smell
it used to do this once in a while a long time ago but didnt do it for awhile and now since the jwt ecu it seems to be worse it never seems to lack power as i can gun it and still feel the ve scream but just trying to drive around normally for those 10min while its warming up is a little embarrasing when its backfiring and smells like poopyes

I don't know about the coils yet as they were pulled in case one or two are bad on the one that I'm supposed to be getting next week (gotta call him later on today)
It's white , hit in the rear, tinted windows, sunroof, beige leather interior (that's going out). Conditionwise it looked about the same as my old one

The water evaporates, micro size glygol chrystals stay. They crave for water like sponges, collect moist from air. Moist will short u electronics.
Seek the polluted place and wash with soap&water, dry. My guess is ignition related wiring, connectors, and/or bad TPS... Whattodo with the TPS? (VE TPS ohms range up to 5kohms)

ok i cleaned the coilpacks and plugs with an electrical cleaner and dryer. the plugs looked normal they are iridiums. So far so good i have the best idle i have ever had with the car i can hit multiple electronics and the needle dosnt move buuuuuuut the car dsont want to start up right away now unless i give it throttle. im going to clean every connection with the cleaner dryer and see where that leaves me.

no the starting problem has been an issue for about a week maybe two and i just drove the car before and it wasnt warmed up and it was doing the backfiring thing again but then once it was warmed up it ran perfect then i got to work and noticed i was leaking oil and my oil pan gasket is leaking easy fix thankfully but i doubt that has anything to do with my problems so 2moro i am going to clean all the grounds and clean all the electrical connectors and see where that leaves me

My guess is still the coolant temp sensor.
Check for codes. Possibly a code 1-3
Mine backfired, had trouble starting, acted like it was flooding -- a lot of the same stuff it sounds like you are going through.

replaced the coolant temp sensor and it still runs the same and its getting worse today i would accelerate adnd it was stutering on me or when i would engine brake but as usual once it was fully warm the car ran great

i have a feeling it is a coil but y would it run normally when warmed up if one was still bad wouldnt it always run like crap
im not trying to shoot down the coil pack theory becasue i have a feeling its that but just tryingto make sense of this
at the moment im cleaning out the tps sensor and trying to test it but my multimeter isnt working right
also how would i find if one of the coils is bad i took them out and cleaned them and tere are no signs of cracking and they look in good shape

well i cleaned the tps out and the car started right up and it was completely cold and ran good accept for a real high idle of 1500 so hopefully this is the problem im crossing my fingers i tryed adjusting the idle but i wouldnt go down?

Maybe your IACV needs to be cleaned out? If you remove it, be sure that you have a gasket IN YOUR HAND before taking it off. They usually take a few days to get from the dealership. On mine, I removed the TB and IACV, cleaned both of them thoroughly, replaced both gaskets and put them back on. It drove much better, idle problems stopped (mine had a high idle -- wouldn't go below about 1500 rpm, even when warm). I just recommend this, because it can't really hurt and doesn't cost a lot. The gaskets are like $8 for both.
You do have some weird symptoms, though. Like I said, my coolant temp sensor totally screwed things up for me. Hopefully, you can get this pinned down.

i cleaned out my iacv a couple months ago i could probably do that again to smooth it out a bit but still that shouldnt be the problem
96italia y would my timing be off first u say its the coils now timing if my timing was off my car would run crappy all the time and would lack power but it runs perfect when warm and never lacks power and cleaning out the tps did seem to solve many problem i didnt back fire once and i had no stuttering or hesitation and it fired right up

what r u talking about when did i say anything about the cam position sensor or cleaning shavings off the tps ( i cleaned out the tps just as wiking stated i didnt think it would do anything either but it definetly did) the car seems to run fine now when warming up so infact cleaning the tps helped out a lot
if the timing was off the car would run bad all the time but it WAS only running bad during warming up
i understand the car is misfiring and a malfunctioning tps could infact cause that while warming up
it sounds to me like you are pulling stuff outchur italian butt and ur not listening to what im doing or what my symptoms actually are
ok enough of my flaming so now the car seems to run good while warming up i drove the car twice today after cleaning the tps and had no backfiring or hesitation at all but
1 the car still dosnt want to fire up right away unless i give it throttle
2 high idle while warming up about 1500 but once warmed up its all good

Even if u problem had not been TPS, this feature must be checked as long as cold problems exist. Max is built so that when COLD, ECU reads TPS and adjusts injection by this reading. When TPS reading is crap, injection is sixpackcrap. After warmup, no TPS (except A/T ctrl input)... only O2 with MAF.
High Idle: Your IACV ... input air hose is not sittin properly, leaks. Take off, Re-seat, maybe use liquid sealAnt.

thanks again wiking even though sometimes i cant understand you are one of the most knowledgeable poeple on here im going to clean out the iacv and use sealant on it and report back i also went from a cai to short ram for the winter but didnt reset the ecu u think that has anything to do

1. Once I was in one small eastcoast cafe´. Asked the teen girl at the cash reg: "where are the cups?" She said WHAT??? Rerepepeated 4x. Then I saw em, and took my coffee. She said: Oh, u mean the cups!" Sure mam.
2. At JFK: NO signs, so I asked an official: "Where's the lift?" He was like OOOOO and said WHAT??? I rerepepeated 4x. Then I saw it, and took my Lift to 2nd level. He shouted: Oh, u mean the elevator!" Sure, Sir!
3. Once I was in a maximized .org. Told a friend: "Look at the Tps?" ppl said WHAT??? Rerepepeated 4x. At last my friend saw, and clickEd my Tps link. ...Then he said: Oh, u mean the Tps!" Yes, I do.
And also clic the CD Favorite Links at left...
1+2+3 = what can we learn from this? No offense: Nothin... Keep Smiling, 40% of human communication is lost to miss understandings...

I think the short"er" ram should be used...the shortness of the short ram has in your eyes has; definitive characteristics when proportionate to your maxima and a misfire...
also
Holy hackbusters Batman! To the batcave to seal my IACV will elmers!

But you are able to read what FSM says about IACV: "do not touch it" [=leak ctrl is beyond mech capability]. This means even minor leaks are not allowed.
The leak could be in the air input hose. I suppose u did not touch butterfly zero adjustment? (Has to about touching TB walls.)
ECU edit: I think the 3gen ECU is mostly stupido. But ECU reset is =batt off for 30min.
