Little problem after x pipe install.

[SLOW95GTS]

Ok so after I installed my off road x pipe, I've been having a slight issue with idle. When I have it in gear and am doing the normal driving ( clutch out, gas in) the idle goes down like it wants to shut off and then it catches its self when I give it gas. It also smells like its running rich when I start it in the morning or after I haven't driven it in a minute.

Any help is appreciated, by the way I did a tune up after and disconnected the battery, also cleaned the mass air. I'm gonna replace the intake, rockers, headers pretty soon so I'm trying to fix this issue before I run into anymore issues.

I wouldn't be so quick to assume that something is wrong. After making a major change to the car's exhaust system, it will take a little while for the "adaptive learning" to adjust your settings accordingly.

Or its leaking at the head.

Like Deep said, i wouldn't jump to any conclusions just yet. When you go off road or even straight piped, especially at first, your going to be running rich, there is less restriction to the motor blowing out, so now it finally has the chance to breathe.

I've swapped an o/r H and catted H on and off mine several times and never had any idle issues. Sounds like a vacuum leak somewhere.
Your smelling fuel at start up because you removed the cats and the emissions is in open loop at start up.

The thing is, I installed the x pipe two months ago and I've been having this since. I'm gonna replace all the vacuum line while I'm changing the intake, hopefully it'll run way better after.

Agreed.....
