Doesn't run with CAI

1397 Views 3 Replies 4 Participants Last post by  312stang
I recently (today) put a BBK cold air intake on my 2010 V6 4.0 mustang. Everything connected fine, no problems with installation, but the second the car hits 1500rpm, it stalls and dies. I can't hear any vacuum leaks but I haven't looked yet. It's very consistently at 1500 which makes me doubt a vacuum leak. No check engine light or service light. Any ideas?

Some aftermarket CAI kits require a custom tune in order to run properly. If yours doesn’t, then I suspect you have unmetered air entering the system. When this happens, your MAF can’t send accurate information to the PCM and your calibration is ineffective. Please investigate these possibilities, and if all else fails, you should return the car to stock, and get a refund IMHO.
