Quick cel flash after prochamber install

slikirish · February 20th, 2010, 07:45 PM

I got the prochamber installed today and of course I've been driving around a good bit to listen to it. On 2 occasions the cel has just flashed on and off real quick. The cel was illuminated for maybe a second. It did it once while driving and the other time was while idling at my house. The dash scan doesn't show any codes except p1000 which I don't care about.

The tune I have has the rear o2s disabled and I know we plugged the front o2s in the right spot since they never came off the car. We unscrewed them from the stock h while still connected. The rear o2s wouldn't reach to be plugged in so we left them unplugged and zip tied out of the way until I order o2 extensions.

Is this just the the ECM picking up that the rear o2s aren't hooked up and then the tune immediately over riding that or is it something else? I've also noticed per the dash scan that the coolant temp is running a few degrees hotter than normal. Such as at an idle it peaked at 206 when it never used to go above 202. Is that possible related or could that be bc the tempature here is the warmest it's been since I started using the dash scan?

When the weather gets warmer it is hard to keep it cool at idle. Few degrees is nothing. Flashing ses light generally is a misfire code. Hows it running?

Runs great and doesn't feel like a misfire. It doesn't flash continuously it's just one quick flash and then doesn't come back. The lack of a code is a little odd to me as well

First page bump.

I have no clue man. Without seeing the code. It could be completely unrelated. Maybe a sensor is loose, and loses connection for a split second. You could try and plug in rear o2's even though they aren't used. I do, just so the wires aren't dangling (and need it to plug them up anyways). I would just make sure ALL sensors are plugged in crisply. Maybe check grounds too. And keep watching for the light/code...

Probally because the rear 02's are unplugged.

Ive been thinking it could be the rears. Not to concerned so it's not even throwing a code. Seems like a tune issue. I'll report back after I get the extensions and get them hooked up.
