Re: 1990 Prelude High Idle and fluctuation JSPEC motor

I found the problem!!!! I checked the injectors and fuel pressure regulator to rule them out. Also the MAP sensor and all other items.

I then sealed the throttle body opening and it started and ran with no air flow coming in there. I assumed then that the intake gasket was no good or not sealed properly.

When I bought the motor, it appeared the intake was torqued down. Little did I know that the person who did this neglected to purchase an intake gasket and install it.

I thought about removing and retorquing several times when the motor was out of the car, but felt the other person knew what they were doing.

Hint of advice, NEVER DOUBT YOUR INSTINCTS and take a few more seconds to double check. This was MY MISTAKE for assuming.

Thanks for listening.

Tim
