[clumsy_smurf]

Check the gasket, I think I had one a while back that the gasket was wrong and caused an internal vacuum leak.

[clumsy_smurf]

the gasket between the body and intake right

Yep, i think there are a couple different cut-outs of the same gasket between each model car.

Check your engine on how it revs before you check a motor.

[clumsy_smurf]

well it was idiling perfect. right under 1 grand. then this shit happens.

[Terror]

check for one of your vacuum lines being unplugged... common mistake

[clumsy_smurf]

i did. all of them are in

put your hand over the throttle body covering it. If it idles down to normal then you have a vacuum leak.

If the engine shuts off, you have NO vacuum leaks.

Usually when you replace a TB, its a vacuum leak, you either ripped the TB to manifold gasket, put it on wrong, or forgot to hook up a vacuum line

[clumsy_smurf]

ight, ill try everything yall are tellin me tomorrow. im so confused about it

[AnthonyF]

Like everyone stated, I'm pretty sure you tore your TB gasket or isn't instaleld correctly.

x2^ easiest way to do it:goodjob:

[clumsy_smurf]

fixed it. now i just think i gota vacuum leak cuz it revs good then revs up, then down. back and forth revving

[You_Wish]

idle air control valve maybe bad also..

[EmminoDaGreat]

I would bet along the lines of an extreme vac leak, stuck tb or cable.

[You_Wish]

throttle cable clip come out of the fire wall and get hung up lol seen it happen.

Try adjusting the idle screw in or out some. If not then do what Mike said and put you hand over the TB to see if motor shuts off. If it does then you have a bad IAC, if not then vac leak.

[2jdm4drift]

IAC sounds like its bad... or gasket...

[jadakid88]

fast idle valve

[greasemunkey]

make sure all the vaccum hoses are hooked up

[clumsy_smurf]

ight thanks yall. got it runnin good. now another prob :(...i have no power at all. like i let go of the clutch and all and it just dies. and yes i kno how to drive a stick, used to have a rx-8

[WookieMaster]

beat its a vac leak..sucka.lol

[CaTcH22]

Make sure ur vacuum line to the MAP sensor is on and good.

[clumsy_smurf]
