Engine hesitation

john970 · 01-05-2009, 06:03 PM

I have a JB1 and am experiencing some engine hesitation when the car warms up. It got bad last night to the point it felt like I was on a rough road, like a cylinder was not firing.

Anyone else experience this? I have about 6,000 miles and did beat the hell out of it on the track last summer (at altitude).

I thought this was fixed with later engine builds (08+)?

If you have a Dinan stage I or II, will BMW deny a HPFP warranty claim even though it seems to affect all models?

Can someone explain to me what is HPFP?

Can someone describe the specific symptoms of this?

long cranks
engine hesitation
your car feels VERY slow.

This only happens when the engine is warm, sound right?

A friend has a Dinan stage 2 flash on a 335i and his hesitation was cracked spark plug.
