I recently swapped in a h22a from hmotors .. The engine randomly misses and acts stupid . I believe its something electrical related.. It will sputter when i hit a bump . I can close the hood and it will start idleling erratic and stall sometimes... Even when i slam the door same thing .. I need some ideas of what it could be ive checked grounds they are all tight .. im lost here

 

hmm maybe pull all those grounds and make sure there is good metal contatc underneath, and for the fun of it check your battery alternator and ecu connections.

 

its a bad ground somewhere...check the degree on your dizzy...

 

found it thank god .... it was a loose connection to the map sensor
