Alright, I've posted this on e30tech a few days ago, but I need more help.
I'm running a MAF, SMT6, and LC-1. Other than that we're stock. No vacuum leaks, nothing else I can think of....
I'm running a MAF, SMT6, and LC-1. Other than that we're stock. No vacuum leaks, nothing else I can think of....
So I'm about to leave work, and it's been raining all day, so I think to myself "Ah, great, we're gonna have fun starting this thing up..."
I get in, crank the bitch over, and she runs. Perfect.
But right after startup, the CEL goes on. Perfect.
I sit for about 30-60 seconds like I do everytime, just to get everything going, and I've still got the light on. I try revving it, but it's very hesitant. When the throttle is released, the rpms go down to about 500 and it can barely hold an idle. Eventually it poops out on me, so I check the error code: 1221. That apparantly means EGO sensor.
Well I start it up again, and it still has issues running. But I figure, I'll give it a shot anyways. I can always call CAA if it dies for good.
Driving is a pain. It's bucking quite a bit, and I pray that I don't run into a red light or traffic.
I get into second gear, and it's still struggling, but all of the sudden, voila! CEL goes out and it's driving strong.
Well WTF? Can something just magically fix itself like this? I make it home without any issues, but I'm still puzzled.
I guess I should mention that I recently installed a wideband LC-1, and after doing that I would periodically get a CEL come on for a second or two, mid-driving. Whenever I got where I needed to go, I'd check the code, and it was 1222 - Lambda Control.
Any insight?

Well god damn....
It wasn't raining today, but the exact same thing happened.
This time the light went away when I was at about 4k in 1st gear. Maybe it's load-dependant? As in maybe it is my MAF, and it requires a certain load to fix itself?
Any ideas? I'm screwed if this dies for good...

Alright, this thing it starting to become very predictable.
This morning I start the car up with my SMT6 logging so that I can see if there are any MAF errors. Sure enough, it has the same problem.
But the data from the SMT6 indicates that the MAF is running correctly. It's sending out the proper signal, etc.
So I get in and drive, and slowly accelerate in 1st gear. I reach 4k rpm on the dot and the light goes out, all is well.
I can't think of anything that is causing this... I need it fixed.
I did notice an extra strong smell of exhaust during the startup, but maybe it's always like that and I never paid attention before.
I'm getting a MarkD chip soon, hopefully that'll fix it....
I might stop by the dealership today and see if they have any suggestions.
