Stutters as I accelerate
 

Hi,

I would like to know how I could fix the stutter or like pulling back type of feeling when I accelerate the Jaguar 2003 S-Type v6.

First, stop doing it until fixed.

Next, read codes then watch fuel trims. You need info.

Art, as JagV8 mentioned, you need to get the codes read. Any big box auto parts store will do this for free.

Once you get codes read, post actual codes back here, not an explanation. My spidey senses say there is going to be an air (vacuum) leak. Whatever it turns out to be, I am confident it has been discussed here in depth.

Buy a cheap elm327 too, to be able to do more than just read codes.

Faulty ignition coils????
Worn spark plugs??????

+1 on reading DTCs/data from ECM
