<SOLVED> Stuttering
« on: May 10 2012, 08:27:17 AM »

is it lean or rich?  Does the coolant temp reflect ambient conditions initially? Is the vacuum at normal levels?

A lot of broken parts does not make you a racer; it makes you a slow learner.

Quit getting stoned, or wait 8 minutes or until you are hot before you start to talk; may take a long time to converse with someone.  :atbeer:

Got the metco mini stuffed under the wiper. Will report after a cold AM run.
That may be the original filter I changed out when I did the lines ~2yrs ago.

could not tell anything from that...did the pressure drop at the end of the clip?  I would guess you let off and were coasting?

Were your O2s dead lean during that run as they were yesterday?

What chip are you using?
