After my intake/header/exhaust my car doesn't want to start the first try cold. It also wants to lag down and die. Any ideas???

I have the Secret Weapon intake, a DC Sports header and a custom 2.5" Exhaust from the small bottom CAT back.

Hmm.. Is your sensor correct on your intake? Clutch in all the way? Sounds odd.

Yeah, the sensor is fine. We thought that MAYBE it could be unmetered air, but I remounted the intake to make sure and also remounted the DC Sport header with the copper seal stuff and so I really don't know what's up. Maybe not enough backpressure and running lean?

your intake header exhaust mods are never gonna make the car run lean like when you boost it.
