Ok so i have an 88 turbo2 large streetport three inch intake and exhaust fcd has anyone ever had a pressure sensor go out and can u describe what it acted like when it did thanks guys.

 

Last year I had one go out. Just cruising it started porposing like a dolphin around 40mph. I had to drive home in 1st gear. When I shifted to 2nd or higher it jerked like crazy. I checked it with the manual troubleshooting and it indicated the sensor good. I forget how I concluded it being the pressure sensor, but it was.

 

Thanks bud cause i checked the code on mine cause its been running like **** and it gave me that code
