Car troubles

[DoubtedNeon]

first off, my only real problem right now is that anywhere under about 2k rpms my car bogs and leans out, eric tuned the car so thats out of the question.

but something happened, i dont think i have any exaust leaks! what could be the problem?

[doyle09]

so i take it since this is in forced inductions, your turbo, boost leaks?

[DoubtedNeon]

im thinking its having to do with something turboed because it only stalls up when i enter boost in lower rpms

[doyle09]

how much boost are you hitting at 2k. you shouldn't be really in boost until over 3k.

[LionheartedSXT]

He is using an srt stock turbo, so it probably goes into boost relatively quick given its size.

Colt, maybe check your fuel injectors? Or better yet one of the vac lines connected to the housing on the turbo.

[DoubtedNeon]

i checked that line, its fine. what could be wrong with the fuel injectors? how do i check those?

[LionheartedSXT]

Pulling them from the fuel rail and inspecting them. I was thinking maybe a cracked one, or maybe one is really dirty. I'm just assuming since you say it leans out at low rpms, If it doesn't occur at higher rpms then that may not be the case.

Boost leak test
Disconnect battery and reset PCM
Check injectors (maybe try injector cleaner)
Possible crappy sensor somewhere

[DoubtedNeon]

well, basically anywhere under 2k rpms my car limps, it wont go anywhere and af reads - - - still, also when it comes out of - - - it reads very lean. idk wtf is the problem, i c no leaks in the exaust, possible boost leak?

[dtjackten]

possible bad wideband, if the af reads nothing that is what i am assuming the "- - - " means. if the wideband is not infact reading properly i think ms goes into a "limp" type mode.... but running lean when it comes back "on" does not make sence, i would think it would show rich....

[SlvrACR]

I kind of had the same prob and it was bad grounds goin to ECU

[esteinmaier]

If you can get it down to me a week from Sunday, I'll take a look at what's going on from the sensor inputs, and that should give us a clue as to what's going on.

[DoubtedNeon]

ok, cool.

so next sunday? ill see if i can

still gotta check the exaust im taking it off tom.

[Jamie]

pull your o2 sensor if you can, let it hang in free air, and push the button to recalibrate it. The innovates your supposed to recalibrate every 6 months or so.

Also there is a rare time that it runs so rich that the sensor will read lean. Limp modes usually dump fuel instead of cut it

[T-Nasty]

the --- means an off scale lean or rich condition.im sure eric will get you fixed up if its a MS issue. What is your fuel pressure at idle? are you running a RRFPR?

[DoubtedNeon]

how do i recalibrate it?

[Jamie]

If it is one that can be calibrated, expose the sensor to free air and do whatever calibration sequence that your manual says.

For the LC-1 it has a button that you push. 1. expose sensor to free air. 2. Push calibration button. 3. watch status LED blink a specified number of times saying its calibrated (dont remember what number of blinks.

so if you look at my pillar pod I have the gauges themself, an LED, and a button. The LED is my WBO2 controller status light, and the button is my calibrate button. (o2 guages is second one down in stack though)



Hope it helps

well, my wideband is callibrated from the factory, so that couldnt be the problem.

still have that problem

re introduced the coolant sensors to the system the other day, that seemed to fix some of the running rich problems.

every time i boost in a higher gear, as some ofu know, i have a strange ticking sound that is not detonation.. im assuming its the turbo wheel banging around in the turbo. ill check to see if that little bastard has play today.

im at a loss for what my leak could be comming from, im thinking im gonna stay up tomm night or tomm morning and try to figure this problem out.

[DoubtedNeon]

just a little update, the ticking sound went away... just sorta faded away.

still running strange under 2k in any gear.
