Dead Dash!!!

[98.5]

my gauges started acting funny today, all gauges drop all lights come on and trip/odometer flashes. im going to check for bad connection on the gauge cluster in a few min. but i have a bad feeling that its the PCM. Anyone else have this problem or have any ideas? also alternator is still charging(fuel pressure does not drop, it drops 2psi with key on/ engine off) and no performance problems.

Any codes?

no codes, i took gauge cluster out put electric grease on the connection, and Ive drove 60 miles this evening with no problems, i guess i will see tomorrow if it does it again

ive put close to 1000 miles on since first had the problem, it hasn't done the same thing again but my odometer has went from 210k miles to 278k miles :think: but trip hasnt changed(except for miles actually driven.) im kind of puzzled is the mileage stored in the pcm or in the gauge cluster? i was always under them impression that it was in the pcm. i also forgot to mention that a couple years ago my lift pump completely quit working. i ended up cutting the harness for my air dog and ruing a signal wire for the relay to the power lock circuit. mike or anyone have any incite? the mileage isnt that big of an issue right now other than keeping service records. but if i replace the pcm with a used pcm will the mileage change? id hate to buy a used pcm out of a junk truck with 600k miles, and if i ever recited to sell the truck it show over 600k miles

i replaced the pcm and the odometer still reads the same

Mileage is stored in the cluster.
