Manifold gasket????

[gungfusemaj]

Ok if you look at my previous post I am having a high idle problem....could it be possible {I'm hoping not} that on the lower manifold that the "end "gasket that did not come with my kit,{I was told not to use them but to put excessive amount of Rtv sealent instead} if there was a slight air leak could it cause a high Idle I have checked everything from head to tail the only thing That I have not checked yet is ny O2 sensor's.......I could use some input on this because I really do not want to pull all of that shiaat apart again unless I have too.

When I changed by intakes on my last 5.0 I just used lots of RTV also. I never had a problem. I don't think that would be your problem. however, I'm no certified mechanic either.

If you were leaking vacume from the rear of the intake or where you used the rtv, you would also be leaking oil. Assuming you are talking about one of the end gaskets. Did you correctly adjust your base idle and tps?

This was a reply to your earlier post. You have to have a volt meter to adjust the tps to the proper setting. The throttle blade has to be set for the base idle first. With the engine warm disconnect the harness to the iac motor. If the base idle is set correctly it should idle @ approx. 700rpm's. If not, adjust the idle screw on the t/b to the correct rpm. Now with the engine still running, connect a volt meter. Black to groung and red to the tps signal wire. Maybe green depending on year. The other 2 wires are ground and your 5 volt reference. rotate the tps until you acheive .95 -.99 of a volt and tighten down the screws. Now plug in the iac motor and if that's functioning properly the car should idle normally. Hope this helps. You must adjust the base idle first before the tps adjustment!!!

well i am a certified mechanic

There is no engine vacuum where the lower intake meets the block. Below that is the lifter valley. If there was a bad seal there, it would leak oil. Check your TPS and listen closely around the engine for a "hissing" sound.

OK the adjuster on the Throttle body is back as far as it will go in other word the the"Butterfly" is closed completly ....now the sensor on top is adjusted to the far left,now say I get a volt meter on there HOw do I adjust the voltage by moving it left or right or what I am going to replace the O2 sensor's and check for codes, hopefully this will help. Thank you Gsx for that bit of info there is no leak. I have checked all hoses for they are new and tight as a frog's AHOLE .....would bad sensors try to over compensate??????
