92 EG Idle problem
 

Hey everyone, Im having an issue here.

I have a 1992 EG hatch with a 99' GSR swap.
I've just done a Skunk2 Intake Manifold swap along with a 68mm Omni TB.
I have all the plugs plugged into the right sensors, all lines everything connected.
I am using OEM gaskets for the manifold and the Omni gasket for the TB that came with.
I've adjust the new Omni TPS to the same v as my old TPS.

my issue is; when I start the car, its starts but Idles very low, maybe about 3-500, and the motor tends to shake.


Anyone have any idea what could be the problem? It would be much appreciated!

CEL codes?

Does the engine idle to spec when warm?

Does you engine have an FITV?

Have you cleaned the IACV?

Re: 92 EG Idle problem
 

no CEL.

once i start the car with the OMNI TB, it idles low at start. but if I put the stock gsr TB back on with the stock TPS it idles just fine like it should

You answered your own question right here. You can't start putting all these air/fuel altering parts on the engine and not get it tuned to make use of and operate properly.

My buddy has the same set up with a blox manifold and his ran perfectly fine untuned.

Re: 92 EG Idle problem
 

So you say. But... 1) we're not talking about your buddy's car and 2) how do you explain why it only runs correctly with the stock throttle body?

Maybe you should talk to your buddy and see where you're going wrong. But If the manifold was different, then it's not the "same" setup is it?

And aren't you supposed to install the OEM TPS on the Omni TB?

theyre all ITR reps.

The omni came with a new TPS . I'm guessing i need to adjust the Idle screw. imma try that tomorrow.

Your saying I have to get a tune to be able to run my 68mm TB ?
