I was on the highway last night al by myself after I got out of work around 12, so I decide to test my 88 TII. This car is in immaculate shape with only 78k miles. But anyway I'm seeing how it does in fourth, and right around 4800-5000 I hit a very hard hesitation. It feels like I'm hitting a wall. I have heard similar descriptions of fuel cut, but this car is completely stock. Any ideas?

 

hmmm...Sounds like fuel cut.

Odd..What was your boost indication?

 

Right about where it always is, maybe 3/4? I can repeat it too so it's not a one time thing.
