well, It's up, It's down, It's up, It's down.... all the way home.
I'd shift down into 3rd to bring the rpms up and the guage would jump back up to 14, then it would drop back down after a mile or two to about 11, I'd kick it back into OD and let it ride for a minute, then drop it back into 3rd and the dash and guage would go back up.
All this over a 30 mile trek home. Then it settled back at 14 like all was normal. But never a check engine light again.
Kinda wondering about a short or bad connection. Or what are the symptoms of a Regulator going out?
