Question for Steve Brotherton
Thanks for the reply.
On the cold start enrichment.. both temperature sensors read the same within 4-5 ohms, hot or cold and seem to be within the scale shown in the manual.
(I have good test equipment, my work is in industrial process control 22yrs). I would think the computer would set the cold start at a point depending on the temperature feedback. I'll check the manual for values and see....
I understand about full throttle...the switch kicks in...and the loop is opened.
For the normal driving and idle difference > 5 mA... you think MAYBE fuel pressure or injector flow could be somewhat off the normal ? And I should have those two checked ?
