Scroll to the bottom of the page.....the searching is already done for you courtesy of the website!! There are even 3 threads with the EXACT SAME TITLE as you!!

 

happens too me cuz my clutch is messed up.Other than that not too sure.

 

Found this:
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.

Hope it helps.

 

Ok dont know if this will help anyone? I called Mazdatrix tech and they said due to all problems i was having change the TPS i get a new one next week if that fixes the problem ill post it. I have all ready changed the grounds and still there is a problem. Thanks for the help
