Car is getting worse.. >.<

[eclipsemodder]

today when i was driving home from work and the car was cold it was bogging down so badly down to like 400rpms or less it seemed that i had to keep my foot on the gas a little while i had the break on at lights to keep it from dying.....can this seriously be from my o2 sensors? i feel like its something bigger. only thing besides the obx header that ive done recently is change my spark plugs to ngk irridium's....could those be causing a problem?

[DustinH]

If you gapped the plugs right then they should be good. The o2 sensors do play a huge part in how its freaking out. Mine did it when i had that header on. Have to tried double stacking the spacers?

[eclipsemodder]

well i only bought the set of two off ebay... soo id only have 2 on one side and none on the other lol, ive been reading though that this can be caused by vacuum leaks? so maybe i need to check my intake? and can exhaust leaks farther down the exhaust pipe cause this issue even tho its passed the o2 sensor?

[07-eclipse-newbie]

man...stories like this mkae me scared to instal my rre headers...should i be worried?

[eclipsemodder]

im also thinking it may be intake related because the code just says bank 2 it doesnt say sensor 1 or 2 or whatever.

[07-eclipse-newbie]

and this problem sounds ike a spark plug problem...they could be flooding, missfireing, stuff like that...i would check that first cuz it would be easier to check.

no your doing the right thing and not buying the cheap pos header lol. RRE header u should have no problems..

[eclipsemodder]

and i didnt know i need to "gap" the plugs? uhoh...lol did i fuck something up?

[Daxenth]

o2s= ecu reading. if that is fucked. yes your running and entire combustion will freak your car. stack one spacer on each plug. if that doesnt work. go get some 18mm defouler plugs, bore one out. and stack it on the other plug

intake= check your maf sensor. make sure its not imploded.

if its a pre cat exhaust leak, that wouldnt do that but it could throw a code. post cat. it will just be annoying

[eclipsemodder]

yeah i already have the 18mm defouler's bored out and also the ebay ones. and what would an imploded maf sensor look like lol.

[eclipsemodder]

and do i need to gap the ngk irridium plugs?

[DustinH]

NO dont gap them

[DustinH]

My bad on that one...My head was in my ass when i said that !

[DustinH]

[Daxenth]

ask dustin lol. i think he said his MaF was all brown and burnt looking. he was getting shitty mileage and idr if he coded or not

[eclipsemodder]

lolll okay, but can there be problems if u dont tighten the plugs down enough or if u over tighten?

[DustinH]

If you over tighten you will strip the threads and hate your self FOREVER
If you dont tighten enough you shouldnt be working on a car.
Make sure your 02 sensors are plugged in haha that will fuck shit up.
Get some plug foulers dont drill them use them in the header then use the ones you bought or drilled then put the o2 sensor in

[dejectedangle]

If you have a ses light plug that bitch in and read it..... If the car runs good when cold but when it warms it starts running like shit it's one of the 2 o2 or maf sensor.... Get electric cleaner spray and spray down the maf sensor that's easy to do

[eclipsemodder]

its kinda opposite. it runs like shit when its cold then gets better.

[dejectedangle]

O well the easiest thing to start off with is spraying the maf sensor.... Do you have a check engine light

[zumspeedsupra]

Yea you dont have to gap the plugs. I have spacers on my OBX headers ill go take a pic for you. The spacers HAVE TO BE on the sensors with the black wires. I had to extend one of mine to get it to reach. Did they extend one of yours? If so make sure thats not backwards...

[zumspeedsupra]

[joeyb]

you do not gap iridium plugs.

it could very well be an exhaust leak.

and yes, if your o2 sensors or MAF aren't telling the EcU what it expects to see, then it could cause the probs you are describing.

[JoeyC]

now that i think about it i had my plugs changed i hope those effers gapped them what will happen if they didnt would i know by now?

[eclipsemodder]

waaaaaaaaaaaaaaait a second....zum u have the o2 sensors crossing over? mine are put in differently....did i do it wrong?

[eclipsemodder]

can u tell me which sensor goes where? cuz i think i didnt put my black one's in the right places...?

[DustinH]

lol no thats juts how he decided to do them

[eclipsemodder]

damnit lol easy fix dream shot downnn

[eclipsemodder]

i got a new battery today im gonna put it in soon cuz my car barely even starts, and im gonna check the spark plugs and my intake for leaks and how many of the gaskets or whatever they are called did u use on the header to seal it?

[dejectedangle]

^ plug the obd tool in dude stop guessing if any of that stuff is fucked up the computer will tell you EXACTLY what's wrong.... Ur just making it a pain in the ass..... Go to autozone it gets done for free

[zumspeedsupra]

Not sure as to the exact order. Had a shop put mine on.

[eclipsemodder]

i already used the obd tool.....it said bank 2 too lean. didnt say anything about a sensor just said po174 bank 2 too lean

[eclipsemodder]

also the second spark plug on from the left was a little wet. idk if that means anything.

[dejectedangle]

Antifreez??? Oil?? What color is it pics?

[dejectedangle]

Well it's deff a exhaust problem I don't think you can mix the o2's up don't they all have different length wires? I know it's impossible to mix em up on the GT

if they are idridium plugs they aren't suppose to be gapped at all.

if they are gapped in correctly, then your engine MAY not run correctly - misfires, ext.

[eclipsemodder]

its oil, and ive tried all the tips ppl have said with the o2 spacers and double spacing...this car has given me such a headache. and its getting progressively worse, it use to idle fine but now it nearly dies and sounds like its choking and the engine moves a ton just at idle.

[Fizzix]

Forgive me for joining this thread late, I'm new to the Mitsubishi Eclipse world. As I see it, the problem you are having is the car is idling too low and it wants to stall. Is this correct?

You may want to look at the idle air control valve (IAC). I'm not sure where this control valve is on the engine (it's after the throttle plate, usually on the intake manifold somewhere) or if Mitsubishi even uses one, but if it does this is the sympton you get when when they begin to fail. Basically they act like a controlled "leak" allowing enough air into the engine when the throttle is closed so it can maintain a correct idle. Let us know how you do.

man take it to midas or some muffler shop and see if they can find a leak. that is what I would do. it's almost like your running the F/IC and the MAF voltage is set too low....but you aren't so I don't know... check for exhaust leak, my 2 cents.
