alright heres the problem i have a 91 hatch with a b16a2 i keep getting dtc 3 map sensor problem so i went to a buddys house and got another map sensor and the code is still coming back but whats weird about it is i will be doing 60mph steady cruising and the car will start to stumble badly like its missing but if i turn the key off and turn it back on the car will run perfectly fine i work at a honda dealer and have done all the troubleshooting that was available to me and getting no problems with anything because the car only acts up every once in a while so its hard to get it to act up when i'm at work so i have all my tools at hand so anyone have any ideas

 

Maybe a loose connection down by the ecu for the map signal wire. Check make sure the pin is pushed in to the plug all the way... or maybe a bad ground for the map sensor

 

i checked all those things already twice lol
