Shuddering under acceleration

help me · 06-24-2013, 05:34 AM

I'm having issues with car shuddering quiet bad if I accelerate hard. Was only doing it on hard tune but now doing it in while running OEM computer. There are no codes or messages. From what I've read it's possible it could be the HPFPump
Anyone got any ideas

Could be anything plugs, coil packs, injectors, bad gas, carbon build up... I ended up replacing the plugs, coil packs, and injectors (under warranty) and paid to have the carbon cleaning done and now the car runs like it's brand new.

Check coil packs. Happened to me with a tune but caused a cel. I would check coil pack and plugs

Sure it's not wheel spin with axle tramp?

Or traction control?

+1 ^ With no codes could be TC. My car does the same thing unless I press the TC button.

Car finally threw a code for misfire on no 5cyl so swapped coil and fault followed the dodgy coil. Fitted new one yesterday and cars back to normal
