so I have a 2007 dodge caravan. If I'm sitting in park and rev. The motor gradually it start stumbling at exactly 2400 rpm . Driving down the highway and as soon as it reaches 2400 rpm it does the same thing . It will shift then when tach hits 2400 same thing. Sounds like a rev limiter. Fuel pressure stays right at 60 but fluctuates about 2 or 3 pounds while it goes into the stumbling again. Any suggestions would be appreciated. Thanks
