rotary tech question
I have this hesitation whenever I accelerate right around 3500-4000 RPM
i found this under the sticky and i was like stait thats my problem. but my new problem where is this pressure sensor at. if any one can set me up with a pic it would greatly be aprciated. thanks marshall
The dreaded 3800 RPM hesitation is cause 90% of the time by poor ground connections between the engine, the battery, and the car. Clean or replace all the under hood ground connections. On 86 model year cars , replacing/regrounding the pressure sensor's ground wire has helped (do not re-ground a 87 or later model year). If there is still a problem after that, look at cleaning the fuel injectors and (on a N/A) that your 5th/6th ports are operating correctly.

Hmm this looks like the next how-to someone needs to post to the GV project. Without posting pictures, I'll say the pressure sensor is a small black rectangular sensor bolted to the front of the passenger suspension tower. It has a 4-wire plug and a vacuum tube coming out of the bottom. It also says "PRESSURE SENSOR" on its top sticker.
