Throttle pulsing??

(1/1)

Camster:
Occasionally on my 04 GT,when I start to accelerate from low rpm in first gear,I experience a significant on/off throttle thing that just won't straighten out until I back off the throttle, or shift in second,etc. Ayone else familiar with this? -Doesn't happen in any other gear.Thanks.

rmodel65:
is this a manual tranny car? do you have a broken motor mount>?

Camster:
Manual. had the same thought,but think it's electronics related.There since the car was new.(and I've had cars with broken mounts and this behaves entirely different.
Unrelated observation(?).When coasting to a stop,exactly at 1000 rpm, it feels like the car loses engine braking.

crzylx:
Alot of the Mustangs I've driven since the mod motor was introduced have had that problem. I've never been able to figure exactly why - but I suspect it has something to do with a lean spot in the MAF Table.
