Quick question.. maybe somebody here has experienced something similar. When i first start the car and driving it around everything is normal. Im running an autometer a/f ratio guage. Well, after about 10 or 15min of highway driving, the guage goes all the way to lean and never comes back up! I cant figure out what could be causing this to happen everytime! Although, the computer is NOT throwing any codes, it is causing some jerkiness during mid-throttle.. any ideas?
