It happens when i go WOT, (my CE light comes on then also). is the rich mixture normal or should i be looking for some way to even it out? under normal driving the gauge reads fine, sometimes a light in the green, but nothing too big.

 

whats the CEL codes pull as?

 

when i check when i got the car a couple months ago i got a 13, 30 and 33. pressure sensor, and solenoid codes. could it be coming on because the some of the solenoids no longer go to anything ?

 

no longer goto anything? the solenoids may be checking the CEL because a vac tube might have come off (you'ld probably notice a high idle at certain times, depending on which solenoid it was)
Pressure sensor might cause the car to run rich, not sure though. Some guru will reply with that info.

What mods have been done?

 

I believe thats perfectly normal, and where it is supposed to read. I have the autometere A/F gauge in my T2, and when normal driving, the gauge would just bounce around everywhere. Under WOT, it would go about 3 bars onto the stoich side. My friend had it on his GSL-SE and it did the exact same thing.

 

mods are in sig, all the emission stuff was removed, thats why the solenoid CE lights come up i believe, because they aren't doing anything.

how do i get the CEL to keep from coming on, besides pulling the bulb or something similar?

 

My car reads 3 lights into the rich, all the time.

 

those A/F gauges aren't too accurate tho.
but mine reads rich too.

 

The autometer a/f in my TII did the same thing. You're fine. DO NOT attempt to tune your car with that thing...

Yeah, I was gonna say the same thing. Threads about auotmeter A/F gauges and similar that use the stock O2 make me cringe. The stock narrowband O2 is ONLY accurate within a VERY narrow range, that range being right around 14.7:1 (stoich). In other words, the sensor will tell you it's rich, and it will likely be right, but rich could be anything from 12:1 to 14.6:1. Both are technically rich, in the eyes of a sensor designed to tell the ECU when the mixture is stoich.
