intercooler install funny idle

[actionbstard]

car came in one day and it had those cheap couplers turn and he had a leak.We checked all couplers and they were stupid tight.all good but during pressure test it look like a leak.We took off all couplers and one had a small hole in it.There was no way to see it when it was installed.Good couplers problem fixed

If your idle is lower then before and not bounching then I actually think your original was leaking and the new one isn't. If this is the case you'll need to adjust your IACV to bring the idle up, I believe the rb20det is supposed to be around 600rpm.

Make sure your couplers are stupid tight. I thought all mine were, but two of them (despite being really really tight) leaked a bit. tightened them more and all better.

This happened when I installed my front mount, too.

+1 good first step

Try a pressur test on your piping... Kinda sucks having no afr gauge when **** happens

Well when my brothers IC piping blew off, he was running reaaaally rich. Looked like a diesel (lots of black smoke coming out the back). But yet again, it blew completely off, so not really a small leak.

checked all couplers but its kinda cheap piping and couplers for now but i didnt seam to find anything loose or leaking. im not sure if its running that rich i dont have an air/fuel gauge or anything. just seams to idle quite low

[Saskacer]

Check for leaks around your couplers. Is it running really rich?

so i finally got my new gtr front mount installed after waiting for a nice day to do it but i noticed that my idle is really low now. its about 300-400 rpm and was around 900 before, should i adjust anything because of the intercooler?

motor internals is stock and ecu is stock at stock boost. just bolt on parts like exhaust and intercooler, flywheel and clutch, bov etc on it.

any suggestions?
