Ok mr,
she ran GREAT sat. Now she’s dropped the ref vol AGAIN. Totally rewired tps. Maf ect and o2 pulled from back of ecu. She’s definitely in limp home mode now. Don’t know why it ran so good sat. Didn’t seem to affect it at all that the other sensors weren’t on there but could smell that it was runn rich- lean... something. Wasn’t getting any black smoke. Ummmm. Ref is down to .08 now. Totally lost again.... bad ecu??? Had a rebuilt one in there ran great for couple days without the maf plugged in minus the hiccup at say 3500 rpm then it dropped the ref.
This time..sat... it ran even better with the rewired tps...and no maf ect and 02 sensors.
Maybe this ecu is shot???? And the other rebuilt one blew because of the bad maf??
Bout ready to scrap this ol girl. Tired of throwing money at it.
Definitely appreciate your insight. Thanks
