Is your MAF plugged in?

 

I didn't touch the MAF sensor, and i already checked that. It is really driving me nuts. My dad said it sounded like the engine was starving for gas, but when ever i shut it off or its kills it makes the big vacuum sound. I work on this ****** car evey night trying to get it to work, i got it down to 8 minutes to take her apart and 7 to put in back, i've down it so much i could do i blind folded. Its gotta be something i did though, becuz it ran great before it took her apart. :frown:

I looked into the smoke pressurization thing and only shops have that, i would look like a fool takin it in after all those mods. :shakehead:

 

When I put my exhaust on I forgot to plug the MAF back in, and it would start for a few seconds, then die, sounded like your problem, but I guess not. Are you sure you got everything capped off, and going to the correct place? So you think that it is something to do with your TB mod?

 

If there are any leaks at all in the duct between the air flow meter and the TB the car will run like crap.

 

-----I checked my MAF sensor- plugged in.



-----Checked all plugs and vacuum holes no leaks at all, used several methods.



----- I was spraying carb choke to test the upper to lower intake manifold seal, and after i took it apart again I noticed carb cleaner was on my gasket! WTF? I have a new gasket, no old gasket on there( smooth ), I used a torque wrench on the nut and 4 bolts, to specification. I am almost certain the vac leak sound is coming from that area. It must be that damn thing. So i used a lot of RTV gasket sealer and didn't squeeze it out, gonna let it sit and form for a week, then torque the bastards down.



gonna try and narrow it down once again.

ps. *spark plugs still fouled by atf trick*

 

well dipshit I think u severely fucked it up. Just kidding man ill take it apart with u again if needed and check all the vacuums!

 

shutup no rx7, *cough* i mean kenny..... j/k replaced plugs and will find out friday when the RTV is has turned in a gasket. keepin those figgers crossed

 

finally got this **** down. I was using some carb cleaner again. This time i noticed the engine rev up a little and start sounding better. becuz i had a board against the gas pedal, instead of a friend revving the engine. I can see the carb cleaner suck into the intake, wtf?

- what sealant do u guys use? the bare gasket doensn't work ( and yes its clean, dry and everything is smooth )..

- i tried rtv copper ****--- lets just says it is ****...[B]

 

Well at least it looks like you are getting closer to finding the problem.

 

OK! dammit, i finnaly got that ******* lower to upper intake manifold leak fixed. It turns out there was 2 leaks, so i thought the ****** leak on the lower to uppper manifold was never fixed, and sometimes i could hear leaks with the vacuum hose and then i would take it apart and put it together again and i couldn't hear anything, but it still wouldn't run so i thought there was still a leak there. I finally got a vacuum gauge and found out that it FOR SURE was a vauum leak. I have checked all othere possible spots and found the other ******* leak. It was really loud and coming from under the upper intake manifold so i can;t see it or see where the vacuum hose is testing. So i hear the vacuum suck get really loud throught the vacuum hose. I carefully let it still there and removed the upperintake manifold. It seems to becoming from the lower manifold to engine GASKET. WTF! i think there is a leak there. I remember gasoline getting spilt there many times and probably left down there since i could get all of it out. could that fuckiong gasoline have seeped down into that gasket and have eatin it away???



JESUS CHRIST IM GOING TO TAKE THIS ******* PIECE OFF **** ITNO THE GODDAM SHOP BEFORE I TAKE A ******* CROWBAR TO IT!!!!!!!!!!!!
