Today I am diagnosing an issue with the ignition control module on my 2000 Buick LeSabre without any computers. It seems sketchy but the job ends in a success, until the test drive at least...
I’m looking thru lesabre vids right now.. mine has been having random misfires with stalling when I start all intermittently.. 2 mechanics I spoke to think it’s the icm starting to fail especially I messed with the fuel air ratio by putting new sensors on that have been failing for a long time now. I hope that’s what it is, all of its raw data is being checked and diagnosed right now at the shop
