Idle drops and drops till it dies

Should be tuned for a 110mm MAF housing if you want to check with your tuner.

If BAMA performance cant tell the difference with the JLT 2 and JLT 3.... I guess I should be looking for another tuner....fak!

I'm having a similar problem.

For the longest time I've had a surging/unstable idle. It mainly occurs when I have the A/C on then do from what ever gear to neutral and just coast down to a stop. My rpms will fluctuate and every so often the motor will die.

Parts changed:

MAF, Fuel Filter, spark plugs, upstream O2 sensor, battery. Cleaned oily air filter and TB, MAF. Changed battery.

Now the car idles rough if not dies if I stall for whatever reason and wont start easily. No codes are showing up but I was getting a code for the passenger upstream O2, which I change.

Problem with mine was that a bolt snapped off the throttle body (my fault since I trust someone else with my car). It had a small vacuum leak and all is well. BAMA tune is perfect and no complaints there
