more airflow with the hood open?

 

 

I could be wrong, but I think this topic belongs in the "engine" section, not the howto.

Maybe the hood is is hitting part of your linkage?

[justin 620]

That deffinently sounds like an air-flow problem. Did you hear any noises you would expect to hear if you hit the hood on any linkages?

i have a center pull linkage,its doesnt hit the hood when i close it.i agree that when i close the hood their is less air flow,im going to set my idle at a higher rpm and see how that works.thank you guys for your help.

.i agree that when i close the hood their is less air ????????

 

WTF!!!!!!

If this is true it would happen on all my sidedraft equip cars. There alot of air in there.

 

something is binding.

grease up the throttle cable also.

dial the timming up to 12-15 first.

hey guys,i finally figure out what was causing my idle to be off when i closed the hood,my hood was hiting the vacuum hose.the hose had a crack that would expand when the hood was up against the hose.i replaced the hose and the check valve.idles great,thank you guys!
