The other day at idle the motor seems to be shaky? I haven't done anything or changed anything on it. You can't feel it when you drive, but if you rev it a little in neutral you can feel it. I plugged the predator up and I have no codes, and my brother looked at the parameters and he said they look pretty normal. He did say the short term fuel trim looked odd. One bank at idle ranged from
-7% to around -2%. the other bank was reading -3% to around 0%. And the long term fuel trim it was dumping like 20% in. I am not familiar with the parameters so that may be normal. Any suggestion where to start? Only mods are 01 ported intake, k&N, offroad x-pipe. I can't think of anything else. This is drving me crazy. Any help would be greatly appreciated. This is on a 99 cobra with around 46,000 miles. thanks.
