Who all is using Evans Coolant?
Dan,
Do you think my vacuum vents not operating could be causing a lean
condition? I noticed I no longer have a check valve in the vacuum line.
Maybe I should plug the main line going to the vents to check and see.
What is the minimum injector turn on time? I upped mine to 2.0ms from
1.2msand it evened out my idle and I must have gained 20 more seat of
the pants
HP.
