my 02 lincoln ls will run very rough after starting
The previous owner changed all the plugs, all the coils, the intake gasket. The initial problem was it overheated. But I thought they shut themselves off to avoid damage.
I'd suspect the IAT sensor https://www.google.com/#q=2002+Lincoln+LS+V6+IAT+sensor&tbm=shop
If the water was not drained and 50/50 etylene glycol/de-ionized water mix put in there the coolant loop could be corroded with obstructions~ if this is the case have your cooling system flushed and replaced with the proper mix~
I will try both and let you know. thank you.
