Ok so i installed my unichip back into my car after unichip had reprogrammed it. Pluged up the extra o2 sensor bung and i go to start the car and it idles absolutely terrible.Worst then when the bung wasnt plugged up. It is running -21% stft and -42% ltft at idle. Anyone know how i can fix this? Is it a vacuum leak?

 

Im thinking of just switching to the aem fic and have it tuned.

 

If anyone has one for sale that would be great

 

Mods done to car?

 

Im using the turbonetics turbo kit with a dezod intake pipe
