So I recently got a 2008 Nissan Titan SE 4x4. It test drove fine but recently started to act up. While in drive, the truck will not go past 2000 RPMs. It's almost as if there is a rev limiter. It will go through all gears just fine but no matter what gear it's in, it won't go past the 2000 RPM threshold. It takes a hot minute to get up to speed while on the highway. The odd thing is that while the truck is in park or neutral, it revs just fine, well past 2000 RPMs. Has anyone else had a similar issue? If so, how did you get it fixed. Any help would be greatly appreciated!! Thank you!
