Hey guys, I have a 2005 ba xr6t tuned with dump,intecooler And so on.... Sometimes when I cold Start the car it starts fine but as soon as I engage reverse it runs like sh*t and engine light comes on. I have to put it in park turn the car off and restart it! Then it starts fine! Now this doesn't happen everytime on randomly also I have noticed that it idles very low now and a little lumpy. Checked for engine codes via x3 it says none! Any help would be awesome
