Any experts? Please watch the full video for my full description, there is finally the problem in full force near the final third of the video. Also a 30-110 pull in the middle somewhere to keep you interested kind of a vlog deal lol well see where this takes us

i hate my voice bear with me
official 1st time it really does it: 7:00

 

My car does the same ******* THING. I have been told to clean the throttle body. I think there is a sticky thread about this in the 2.0 LSJ forum. But my car usually bounces higher like 500 to 1500rpms sometimes higher.

 

why was the speedometer moving when it did it? Looks like it went up slowly, or were you just rolling? at 7:10

 

^I MAY have been rolling forward, i was on a hill

yea in my case it snot as explaine in the vid i have a new tb cuz i thought that was the issue, it didn't help

 

Could it be maybe the tune? Since the cold weather could be affecting something with the a/f? Im not certain but I don't think I remember my car doing this when it was warm but I may be wrong.

 

no, car compensates for weather changes using maf and map sensors. Tune adjusts for weather on the fly. That's why you don't need to retune every time the weather changes.

 

i like your voice

its gotta do with own electric throttles maybe?

like how there is a delay when u blip the throttle fast say in neutral...but this could have been due to my small exhaust leak haha

 

My car does this too, but only 2-3 times... My AFR goes Full lean when the RPM's drop, And go back to normal (14's) when they return to 1000 RPM's.

 

What have you replaced so far? What tune do you have? (canned, trifecta, HPtune?) What is the CEL on for?

 

Glad some likes it haha. It could def be throttle related since it does it both when i hit the clutch in nuetral or if i touch the throttle. My exhaust leaks are 99.% gone

 

Good to know. My a/f thing doesnt work to quick or too well. Another part of the problem at large. Im sure it can lean out the engine when this happens. Its no bueno

 

Clutch flywheel tob clutch pipe throttle body air filter ive cleaned the maf a few times

Its a slightly modified but not completely up to date with my parts canned tune. FRom ottp for a stage 2. But its obvs not tailored for an intake my exhaust setup my cooling mods etc.

 

I'm going to clean my throttle body next week when I can get to the shop, If not it may be a fuel issue, I do know it was only doing it when i ran 94, It does it less now that i'm back on 91.

 

good to know man. before, cleaning the tb fixed similar issues i was having

 

the pcm dosent compensate for drastic weather changes very well

tuning for a header swap realy isent needed cooling mods do not affect tune i would look at the tune for your problem and dont beat on your car in cold weather the pcm dosent adjust/compensate very well

 

thanks. really hoping its something in the tune since i'm getting it REALLY tuned anyway pretty soon.

as for not beating on the car... probly not gonna happen :lol;

 

It will most likely have something to do with the tune.

 

my car did the surge like thing at idle when I give it gas and clutch in really quick, i was just parking against a curb or something haha quick little rev and popped it out of gear

i tried to rev it up but it just would idle like yours "riceburner" then it just when away

i believe it did this maybe once or twice last yr, didnt do anything to fix it...maybe i got a new o2 sensor

 

wish i was that lucky

 

Sub'd.

 

Idon't know.. I have tryed everything.. cleaning the Throttle body repeatedly, everything lol nothing seems to work. Hopefully yours does not get as bad as mine, mine bounces idol everytime i put the clutch in no matter what i am doing. I went to shift into 5th gear on the freeway and jsut that split second idol bounced up quick then droped dead lmao.. my car just seriously staled threw gear shift at 75 mph on the freeway. It's rediculous, and overly frustrating... I do need a good tune tho since I have my exhaust never had the chance to retune.. Who is running a pretty good tune nowadays?

 

have you all thought that you may have a vac leak

 

check them hoses thats a good tip^

i figured it was a mistake in the matrix, but no deja vu

 

evap selenoid maybe

 

Im yet to actually test it for leaks but ive replaced a line or two that looked cracked, the rest 'looks' ok for now. Just did an exhaust leak test the other day and fixed two little leaks it had. Good insight it could be vac who knows lol

Do u know where the evap solenoid is on the lsj by chance?
