ok I was going to do an intake manifold swap{y7 to a y8}. I ran into problems when I noticed that I had to make my injector wires longer and also some lines longer. I figured that I would ask a friend of mine what to do. so I put the y7 manifold back on made sure every thing was put back together and then I started the car.

soon as I turned on the car it was idling way high and then it started to surge. up and down went the rpm's. know mind you I can see the rpm level cause I have a 99 dx. so I called up a friend steven and he said that it might be my throttle body gasket, cause I never changed it and I just put it back on. he also told me that I have a gasket leak. my question is will this surging thing go away once I change the gasket or is it something eles. oh I also replaced the manifold gasket. And I also looked inside my manifold and there is some condensation or some kind of liqiud. can anybody help me please.

can somebody help me please.

Sounds like a vacuum leak. Get a can of gum cutter and spray all around the intake manifold and any other place you disturbed while trying to swap manifolds. Once the surging stops or idle goes back to normal....find the area you sprayed that made it go back to normal and R&R as necessary.

Take a .44 Magnum. Point it at your motor. Pull the trigger.

naw I dont want to do that. I wanna keep it build it, turbo and be done with it. I dont wanna follow the B crowd. If I see 250+ with this D I will be happy.

You got high hopes unless that motor is built. I hope to god you used a y8 manifold from an auto Ex or you are in for more then you expected with the iac valve.....

lil_greencivic

yes I am going to fully build it. why would you say that. I am using a 5speed ex. I have not put it on yet I just put the y7 manny back on and now it acting very funny.

like he said...you need an auto ex manifold

lil_greencivic

but dont have an auto. I have a 5 speed. can someone explain what problems I am going to run into.

CHAHONDA

you use the auto ex manifold and bolt the y7 throttle body to it and eveything is great. use all new gaskets too
