Car shuts off in idle, hesitates on acceleration, please help :(
i everyone for about the last month, I have had this problem urking my nerves. When I start the car, the idle acts kind of funny it stays around 10RPM but the engine makes a funny noise, like it wants to loose power. So when I go udner the hood and mess with the throttle, it feels like theres a slight delay after the throttle is pressed, not sure if thats normal? But anywho, if I keep pressing the throttle with my hand eventually the engine will stall and shut off. That is what is happening on idle. Now when driving, if I am at a red light or stop sign, and I begin to accelerate, the cars check engine light will turn on for a quick second or 2, the car will jerk and hesitate, and keep driving like there is no problem. If it jerks BAD ENOUGH, a transmission light will come on. And when this light comes on, the car begins to surge, like letting my foot go off the gas the car wont decelerate for a good 4-5 seconds, and when coming to a stop the RPMS take a few seconds to reach back down to 10.
I have went to a local shop that works on Jaguars and has the Jaguar software, and the gentleman pulled a tps code and a maf code. I replaced both, and the problem still exists. I have also changed the EGR Valve, fuel regulator, and fuel pump, no luck there. I have did a oil change, spark plus, 6 new coils, new valve cover and valve cover gasket set and a fuel filter and still seems like nothing is helping me. Has anyone experienced anything like this?? I was thinking the CAT Converter, but took it to a local muffler shop and they said the CAT Being so small, that it wouldn't cause problems like this. If anyone can help me out I would appriciate it, or send me in the right direction. Thank You, God bless

Idle Air Control Valve
I had the same problem, surge/stall/transmission light.
This happened 2 weeks after I bought the car and scared me.
It was the Idle Air Control Valve and it only required cleaning.
My car was previously owned by seniors who only drove 6,000 miles a year.
Did you drive your car every day?
If it sits inactive for long periods, things can clog up.
What grade of gas do you use?
Since my problem 4 years ago, I only run Chevron 94 and I add a fuel cleaner at every oil change.
I haven't had this stalling problem since.
Thanks,
Kevin
PS.
What brand ignition coils did you use?
What plugs are you running?
