Need help running rich

[d-meeks]

Hi dsmtuners, my 95 gst is running really rich when it sets and idles its about 14-15 and then when I rev it it goes rich and back fires and then when i drive it seems like the gas pedel is acting slow and when I start to boost it back fires really bad. Im going to check my compression tommorow and my oil dont look right i think it may have gas in it cant smell it right now since i have a stuffed up nose but i need help asap thanks.

do a boost leak test, get a wideband for air fuel ratios that will help and tuning device of some sort.

I do have a wide ban and a safc and i have already done boost leak but why would there be gas in the oil? thanks

Yah my wideband is at 14-15 and idle and 17 or just the red marks when i give it gas or drive it.

Whoa bud, that's way lean.
My AFR's drop to mid to high 11's under WOT.

14-15 is okay just cruising, but 17 at WOT is an issue.

Is your car stock? is this something new or ongoing?

d-meeks, Higher numbers in your Wideband means lean, sounds like you have some tuning to do with the SAF-C. Do you have aftermarket injectors? Stock MAF? If you are running stock injectors and MAF then zero out all the adjustments on the SAFC and start over, or just go back to running the stock ecu and wastegate boost on your 16g until you can get ECMLink to tune with.

I'd investigate and figure out whats all done to the car then figure that into your calculations when tuning your SAFC.
This should help you out:

My car has been tuned by king motor sports could a bad o2 sensor be doing this

And its stock maf and injetors.

Do you have a tuning device so you can see whats going on for yourself? So you can see cel then fix them do you have any thing other than a wideband ? Do you have any cels a bad o2 will throw a code plus any other cels that show up.

Order a Innovative motorsports wide band kit (I do not work for them ;D) and then you will have a much better way to tune and figure out what is going on.

He already has an AEM Wideband.. why would he need another wideband? It's not going to tell him any different unless his wideband is bad, he's still going to have the same issues. What are the settings at on the SAFC? It sounds like they didn't tune it properly. Is that how to got the car back from them after the tune??
