I have a issue with my 01 cobra. The car has been driving fine up until a few days ago. Ran fine on interstate and as soon as i got off, the car started sputtering. you leave a stop sign in first and it feels like it is hesitant to go but never gets better. almost sounds like the car is drowning. But you can have it in neutral and rev it up and it does just fine. it only does it worse when on a load no matter how small. I put new motorcraft plugs and put new ignition coils and still no help and the computer isnt pulling any codes either. i also ran seafoam too. Any help would be very greatly appreciated! thank you

Might be a coil issue, any check engine codeS?

No its not throwing any codes. And i already put brand new coil packs on saturday and didnt help it one bit.

Since you used seafoam. Which cleans injectors and stuff like that. Maybe when you did a lot of build up from the injectors or fuel filter got unclogged and is now floating around causing it to sputter. Don't know if this even could be a cause but just a thought.

Also check all the plugs that plug into the injectors and make sure they are all plugged in good. And not loose.

Thank you for the information! And i did check them and they were all good and tight. It just doesnt make sense. Its almost doing the same as my 98 cobra i had and i changed plugs and wires and it fixed that problem. But ive done that to this one and it hasnt helped a bit. Im almost wondering if my computer is gone bad. Cause i unplugged my mass air flow sensor while it was running and the check engine light never came on....
