Ive got an Si motor stuck in an HF and the car will start and run, but when i drive it for a few miles and turn it off, then back on and drive it a few more miles, it starts to spit and sputter/low idle then just shuts off and wont restart...any suggestions/answers??

 

loose conections???

bad main relay?

bad grounds?

needs a tune up?

 

Nah im pretty sure the grounds are alright, but what do u mean by loose connections? Not sure of the condition of the main relay. The only thing done to the motor is a milled flywheel.

 

well loose conections....

check all main wire harness.. sometimes vibrations loose cables up....
its a routine check up....
making sure eveyrthing its tight and in normal conditio
