Open the hood and look down the left side of the battery and you will see a black plastic box that will have the ECM inside of it.
no ECM's in a 1981
What all does the ECM computer control on my 2006 Chevy k1500 Silverado
do you have link and program a 88 cilverado ecm when replacing
located drivers side next to battery look down next to fan and in front of radiator
The 2003 Solverado did not come with a 5.5L Vortec. The 4.3 V-6 and 4.8, 5.3, 6.0, and 8.1 were the coices fer the Silverado. The common spots are passenger fenderwell or behind the glove box. Good luck and happy hunting!
its set by the ecm but sometimes the throttle plate has carbon built up and lowers the idle just have your mechanic clean it
Need to know the year and model.
YES it is.
Short some where.
Where is the ecm on a 03 explorer
Under hood on drivers side fuse box
open your glove box..at the back of it you see the ECM.
