Re: Big RPM drop from park to drive???
I took some readings today if these help at all -
Idle in park - currently - 1380 RPM (if I go much lower it stalls in drive w/ AC)
Idle in Drive - 790 RPM
Idle w/ AC on, in Park - 1080 RPM
Idle w/ AC on in Drive - 690
Convertor stalls at 1750
Any thoughts?
I will check for vacuum leaks tomorrow.
