c1500 (forgot the "C")/? 3 engine + diesel, not old engine,
try new distrib ? or fully rebuilt
not told exact part bad.
ICM, sure.
most folks that replace parts inside any distrib, (electronics only()
do so wrong.
it must have the heat sink thermal compound used, (thin)
or it over heats,, rebuilts are best for sure maker CARDONE 1.
the ICM has metal side, that must be thermal pasted.
must.
is use dow 340 compound or better.
dow makes some that is 8x better for the fasted processor made by intel. that run super fast and super hot.
so when I do care parts I use this, DOW TIM> TC-5022
340 up 5022 is nothing less than fantastic. use only thin covering
thin is best, even .002" thick film even use old credit car to do that.
