Symptoms
Only on cold start
Car starts and idles fine
After driven for approx 1 mile and then idled car runs rough
Feels like it's missing on a cylinder
After a minute or so of rough idle/ rough driving problem disappears and does not come back
This problem appeared randomly - no work had been done on the car when it started pulling this.
tried:
-shutting off car and restart when symptoms come up - didn't work
-swapped MAF with known good MAF - did not help
-injector cleaners - no help
-car got new plugs at dealer at 100k (I hope they were platinum - P.O. had done)
-If car is left to idle in driveway up to operating temp before driving it the problem does not come up.
