Re: [DML] Re: Need the WUR/CPR test procedure

[Nick Kemp <nkemp@xxxxxxxx>]

After sitting for a while (like overnight), the car starts as normal and 
idles a bit rough. When trying to drive it it is hesitant, poor 
acceleration , runs rough. About a mile or so and it used to smooth out 
and then run fine (other than the lower more rumbly exhaust note at 
idle). Now it continues to have poor/hesitant acceleration, runs 
slightly rough, seems to have a lack of power and at idle it is not 
smooth. It seems to have a lower exhaust note and more rumble at idle.

I hope that explains it better.
