CEL... wtf?

[Clipse]

Ok, so I just put an N1 catback and K&N FIPK on my car (no aftermarket boost gauge, I know I know it's on it's way) and removed the honeycombs from my MAF. When I first started it, it sputtered then smoothed out. The idle is a little rough in comparison to stock, but I thought maybe my ECU needed to adjust to the new amount of air the car was sucking in. Anywho... I drove it for approx. 80 miles and then this morning my CEL came on! I checked and made sure everything was still in place, which it was. Then I unplugged the battery for about 5 min. and it went away and hasn't come back. I'm still a little new to all of this, so be easy on me if this is a stupid question. Another thing is that my car seems to be running a little rich. Is this all relatively normal? Help me out my DSM savvy friends...

Do you have some sort of fuel control? If not, my advise to you would be to go ahead and put those honeycombs back in there. DSMs run rich from the fatory. When you take the honeycombs out it leans out the fuel map especially in the lower RPM ranges. Thats why it dies and sputters and acts like an ass when it idles.

also there is a lower 02 sensor right before the cat I believe. If you tookt that off without knowing then that also might have caused the CEL.

 

[Clipse]

Oohhh... that's no good! I threw them away. Now do I need to get myself a new MAF? Any recommendations? And am I putting my engine in jeopardy by driving the car under these conditions?

No, I put the O2 sensor right back in it's place. Thanks though.

Try to find some one with extra honeycombs just lying around. I'll even check for you.

Thanks! That's very cool of you...

How can I make my car run richer until I get my hands on a new MAF? Is it safe for me to drive? It's my only transportation...

A S-AFC

This might help, although I don't know how much you have taken out of your MAF..

Great info... Thanks. I was thinking about throwing my stock airbox back on there for the time being (until I recieve my new MAS) to richen the fuel mixture a little. That should make a little diff. shouldn't it?

 

[Clipse]

Nevermind, after I put the airbox back on the car wouldn't even idle... ? Runs better with the K&N.

Good thing you ripped the honeycombs out without knowning what that would do.

 

[Agent Ezzard]

Man you'll be alright. The leanest the car will run are in the first 3K RPM. Just don't drive around like Speed Racer and put your new MAS on as soon as it comes in.

 

[Clipse]

Wow, I triple posted...! Damn, that's a first.

Or... you could be a dick about it

I agree, you don't have to be a dick about it. He made a mistake and he knows it so you don't have to rub it in any more.

According to the Buschur Racing Stage 1 DSM Upgrade Sequence:

<2G Tip!> - Do NOT remove ANY of the honeycombs - the car will not run smoothly without them

Here's a link:

Just FYI for all you 2Gers out there

I ran mine w/o the lower and it ran even better than stock (I used a pocketlogger). Take out the sides though and it won't run for shit
