just had a brand new ecu intalled by a shop, what ever it is isnt hasnt thrown a code at all or the shop would have seen it cuzz they looked all that stuff up on the old ecu and the new one, when i picked it up from the shop the day they installed the new ecu (friday), it was like heaven, the engine ran so good it was like a dream, but then yesterday, first thing it does when i give it gas, hesitate....and did it today aswell... already cleaned the engine with seafoam, didnt help at all, infact made the engine start up weird like extremely soft start and low idle so i couldnt tell it turned over till i grinded the starter lol...
