thats a Air compressor water trap!!! lol... it will do the job though... now back to this rich mixture code... so the guy that did your tune pretty much just changed your timing... i believe a 12.0:1/12.8:1 a/f is a stock wot A/F.... correct me if im wrong?... 14:1 is a cruise or none WOT a/f stock...

if you got blow by going in your intake it could just as well be causing the rich A/F as well... what plugs you runing and whats the gap???

oh and most importantly whats your DTC!!!

I cant think of the gap but they are one heat range colder then stock. the code i think is p172(i think). maybe i should look in to a wide ban and see if what she does now with A/F ratio.

It's running "rich" according to my diablo. But i just went out and plugged it in again the there were no trouble codes that were found. mmmmhhh.... well that's good but im sure the rich code will show up again in a few days like it always does. Now.... i was wondering if there are any direct indicators to the engine running too rich even though the A/F was set to 12 to 1 by RET. Im thinking of pulling the right bank plugs and looking at them. What should they look like if the engine if in fact is running "too" rich.

If the engine is running rich the plugs will likely be black. Why the hell did you order that thing when I told you 2 times in this post you could get it for $12.99!!!! Steeda sells it for $70 plus shipping!!!!

An Old timer once told me that "if you want to own a race car you have to learn how to work on a race car". You could have saved yourself $50!!

Anyway, a wideband is worth the money. You will never be in the dark about what's going on with the car.

When the car was tuned was there 91 in it? You don't add anything to your tank do you? It could be the way your MAF is clocked. Have you tried rotating it? We had an old member who had that same problem on a vortech blown 99 cobra.

Your desired AF depends on your modifications but here are rule of thumb values. NA (12.5-13.5), Supercharged, Turbo Charged, and Nitrous (11.0 to 12.0). I am running on my car 11.9 to 1 across the board...

Thats what i thought they should look like. Yeah 91 was in the car. I plugged in my diablo in again today and i dont have any trouble codes. I dont know what that is about but we'll see. the oil collector was a impulse buy i have a mental moments from time to time. Oh well.
