I have an 88 Thunderbird LX, not a Turbo or Super. It has a 5.0 with around
170k on it.
Last month the temp, oil, and fuel gauges stopped working.
This was fine until last Wednesday it started running/shifting funny.
I figured it was trying to get code from the cluster, so I replaced the IVR,
since that's what brings the usual vehicle 12v down to 5v for those 3
Well, the gauges still don't work, and it still runs/shifts funny...
What should my next step be?
