I just finished installing a Jackson supercharger on my D16y7, but the car idles like crap! The idle jumps between 1,500 and 3,000 and back. It sounds like if I have a huge *** race cam or something! The IAC is hooked up and everything, however, do the hoses to the IAC need to be connected a certain way, or can you just run any coolant lines to it? Another thing, I couldnt take off my crank pulley, and since the JR pulley is exactly the same, I just left my stock one. Would that make any difference? I mean, why would you have to change the crank pulley if they are the same size?


thanks in advance,

Alex

 

sound like a IAC problem... be sure that all your coolant lines are ok... or it could be your timing.

 

The jumping idle could be a vacuum leak...

 

check the gromets that hold your injectors in to the intake manifold they're probably smashed and now they are sucking in air causing bad idle

 

yeah what the two previous said, check for leaks, souds like bad vacuum.

 

I called jackson racing and they said I have a vaccum leak... How would I find where it's coming from?

 

Make sure the MAP and TPS connectors aren't reversed.

Do you have a FIT valve? When I had my blower installed I had the same problem and it was the FIT valve. It's located under the throttle body.

 

basically it sounds like u have a vacuum leak,

I had a problem when I first put mine on, it was sitting on top of the alternator,
so when torqued the IM down it didnt seal properly leaving a vacuum leak.

 

is the FIT valve the same as the IAC? I checked for vaccum leaks with butane from a lighter but couldnt find any.. Could the PCV valve be leaking from the grommet or something? Thanks for all your replies..

 

well theres a valve under the tb,
and one behind it, on the stube,
check em both

 

I was told that i have the wrong throttle body, so I bought an 98 EX throttle body and IACV, but the car runs worse, because my DX has a 3 wire IAC and the EX has a 2 wire IAC.. What should I do?

 

never mind, It was the throttle body gasket. Stupid Kragen computer was wrong!!
Thanks to everyone for their help!

 

hahaa
dude,
rule #1 of autoparts,
never trust what the autoparts store/workers tells you!

 

but the problem is...............I AM THE AUTO PARTS STORE WORKER!!!!!!!

I can assure you it was the computers fault, not me.....

 

go to a real parts house like HONDA
just playin ........when you gonna go to the track again?

 

I'm gonna wait till after this semester ends... So Ill probably go again around the end of next month

 

hahaha cool

so u got it working ok then?

hey u ran 12's with that turbo LS?
was that on street tires or slicks?

 

Ya it's working great... for a DX at least! Ya I ran 12s on a internally stock LS. That was on M & H 24" slicks
