Hi, 1994 Buick Regal Gran Sport starts without problem when vehicle is cold. Once car runs for awhile and gets hot, vehicle will stop running while driving, and wont start again until engine cools a bit (this usually takes about 1.5 hours). what could my problem be?
Thanks
It might be a bad ignition moduale. or could be a bad ignition coil
I have a same f.. problem on my Regal92. Might be a EGR valve which is not opening up when the Engine reaches it normal operat temp. Ignition Mod could be all in one piece or 3 modules on a plate. Check if is functionally on a computer diagnostic Autozone for free. Change all coils & i don't know how to check the crankshatf sensor. I'm tired of this elec luxurious car, but the mechanic function is very resistant that others dealers. [email protected]
