Hey guys,

Yup, I'm new here and I already need help

Here's the problem.

I bought a Powerdyne SC from a shop online brand new.

Had a local shop install it on my 2k Expedition with the 4.6L .

Install went fine and soon I was on the road. I now have a light vibration coming from the break & gas pedal. I could live with that.. Bigger issue is the motor stalls during stops. Like it is either short on gas or air.

I have an appointmet this Saturday for the mechanic to go through it again but I thought a few extra ideas from you people to discuss with him would be beneficial.

And yes, under full throttle it MOVES.

Thanks for any help.

Sounds like a leak between the MAF and the engine. At WOT, the engine runs in closed loop mode, so the leak wouldn't matter but it would stall when idling.

 

Sorry for the lack of response.
Thank you for the suggestions, I will take a closer look as soon as I can.

Much appreciated,
