I have been hearing a Hissing sound when i give the motor load coming from intake.. now back when i did my swap i had to take my throttle body off, and never replaced the gasket.. do you think it is possible that im leaking through that gasket??? Also if that is tha case would it have any affect on the way my car is running.. feels like its running strong sometimes and a bit sluggish at others. any help, advice welcome. Thanks!

 

Bump??? Cmon??

 

?ttt

 

BUMP!! HELP!!!

 

You could have a vaccum leak and yes i would replace that gasket. Your pretty close to where i live. If you have a vaccum leak you car will be running rich.(your o2 sensing a lean mixture cuz of vaccum leak then it compensates by adding more fuel. Does your car backfire at all?

 

also take some carb cleaner and spray around the intake manifold gasket if that is leaking like it was on my car it would spray a little coolant on the back of the firewall. Yes the car will run strong as hell sometimes then tend to bog and backfire other times. the carb cleaner trick is how I found my leak hope this helps...

 

yea it does backfire and bog sometimes.. im going to check all vac lines and replace that gasket.. anything else? you say im close to you.. im on Overland Park Kansas... yourself?

 

i live in emporia. Good luck and let us know after you replace that gasket if it fixes it.

 

i just looked and found that some vac lines were going to the wrong places.. could this have similar effects?

 

Which ones , i know there is three from the charcoal canister and 3 on the other side of the engine for egr/cruise/and egr solenoid(i think).Pcv valve to intake mani and the iabs.Look in the Faq's and there is a vaccum diagram, thats what i used when i did my swap.
