My car would do the same thing on 91 with partial throttle pulls between about 2700 and 3700 rpm on the stock tune and off the shelf OFT tune. So basically during highway driving with any sort of acceleration without downshifting or even maintaining speed up a hill. If I ran the car hard and revved it out I could get the IAM up to 1. On a flexfuel tune and e85 its not an issue.
