All i did when i ported it was a gasket match. I put my intake manifold back on and now it will rev up to 2 grand and back down to idle. Im not throwing any codes. Ive checked and rechecked and im pretty sure i hooked up all the sensors and vacuum lines correctly. My fuel pressure is fine and eveything im baffled. Anyone know what this could be? If it matters my engine is a b16 A2

Also are these 2 sensors hooked in the right places? Or should they be switched around.

 

ita a vaccum leak, make sure you tightened down the Throttle body all the way and arent missing any vaccum lines

 

switch the plugs

 

i have the same problem went i bored the throttle bodie

 

vacuum leak for sure, doesn't necesarrily have to be an unhooked vacuum line, its prob more along the lines of somethin small.. u did a good job in cleanin but also gave your throttle body more room to suck air in right around the butterfly opening (the huge gold thing in there) not any worrry really, try to seal that vacuum leak though

 

are all bolts on the manifold tight?

I tightened down the intake manifold and the throttle body and still doing the same thing.

Last night i wasnt throwing any Check engine lights but for some reason i am tonight

They are a 10 and a 7

Does anyone know if those wires on my throttle body are in the right places or should they be switched around?

 

when this happened to me it was becasue i didn't clean the old manifold gasket from the head, so when i put the intake manifold back on it caused a leak and the idle surged like crazy

Switch the plugs.

 

Ok

 

i got a new gasket so i know its not that

 

Ok i switched the plugs. Now when i start it and give it gas it doesnt rev up. It like cuts out and almost dies when i give it any gas. Any more ideas?

went through this last week. there are several things it could be.
-vacuum leak, esp the coolant lines running to the FITV
-loose or dirty IACV
-bad IACV
-bad TPS sensor

the trick to pinpointing the problem is to cover the holes in the throttle body to figure out which valve is the culprit, or if it's a vacuum leak.

I just took everything apart and put everything back together right.

 

seems that most people fixed this problem by checking the FITV... I had a JDM throttle body, so I didnt have one.

 

To check for any vacuum leak, which im pretty sure is what you have, Spray some carb cleaner all over anything that can cause a potential vacuum leak, and if the engine starts to choke out, then you've found your leak.

I had this problem for a few days now and i finally found out that I had a leak in my FITV and between the TB and IM because I used a b16 gasket for an LS TB. Good luck.

 

Hey guys i fixed the big problem. Now my car drives fine. It idles a little wierd still. I think i must have a tinny vacuum leak still. Now my car will go from 1k-1500 at idle. Tommarow i will look for any last leaks. I think i need to make a slight change on my throttle cable also. Thanks again for everyones help.
