i take it you have a 96-00 civic?

which throttle body did you use?

AznPride

the one off of the ex manifold, one of the sensors doesnt connect , how could i fix it

CHAHONDA

you have to use the throttle body from the dx intake. or just get an automatic ex throttle body. i can show you how to take care of this

I believe you had the map and tps backwards when it jumped to 6grand, the bogging up and down sounds like a vacuum leak. Spray down the intake manifold and look for leaks. I may be wrong about which sensors are backwards it's been months since I've done one, but it"s the two sensors that have the same style plug.


Thought of something else, if you have the intake manifold off of a manual did you plug the holes you don't need. I know one of them is the cruise port on the far right of the manifold facing the car from the front. It's hard to remember all this stuff without looking at the car!!

sounds like a bad IAC to me

Maybe but if he has both manifold's he should have a spare to try, besides that he's not throwing a code 14.

Even so you could still pull your iac apart and clean it with carb cleaner.
