Hey Guys,

I am having a serious issue with my '86 944 N/A seeking to find an idle.

Recently, while over-charging my battery, I must have filled the engine bay with hydrogen gas, because when I tried to start the engine it exploded in the intake system with enough force to shred the rubber intake boot and shatter the throttle switch.

I replaced the boot and could restart the engine but it just seeks an idle position, as if pumping the gas pedal.

I then replaced the throttle switch (which I hadn't noticed was broken) and still have an idle seeking in the throttle.

Have any of you experienced this problem? Is there a sensor or switch that I may have blown that will resolve this issue?

Suggestiions????

 

Could be something with your mass air flow sensor. I found that if mine was dirty inside that it would idle really rough and almost die when stopped. Hopefully thats something helpful.

 

Vacum leak? When the car bakfired maybe other hoses popped too.
