It problem of my bighorn has never been solved [surging motion of engine while idle] and when running at 60kph it seems like is is suffocating due to lack of fuek

Hello. It seems your Cadillac is getting too much air into its engine; causing it to 'surge'. This could be due to a malfunctioning/defective vacuum brake booster. If your Cadillac's catalytic converter is 'clogging'; this will cause the engine to 'surge' too. Good luck and keep me informed; if you want to.

I would have this checked out to make sure they did not damage the computer, the check engine light may have been due to battery disconnect , the idle problem may be due to the same reason, it may need to relearn idle and other sensor inputs that were lost due to battery removal and fuse popping, this should take a day or two of driving it.
if you are still having a problem after that then have it checked.

Clean the airflow sensor. There is a special spray to do this. DO NOT use carburetor cleaner. It will damage the sensor.

what kind of car? possibly a coolant sensor

Landcruiser 100 vx, 2003 model with engine number 1HD-FTE is not starting, I've found out that the fuel pump, starter, battery are all functioning well. Where next should I look at.

check your idle air control valve

Car may be running lean, I would check the air filter, and replace if it seems excessively dirty (should be done every few oil changes) and check the 'pipe' that connects the air intake to the engine. If there is a crack or hole, it may cause your truck to run lean. Also, if your check engine light is on, and it is the oxygen sensor, a faulty sensor could give bad feedback to the system and suffocate your engine, making it run too wet and causing it to stall when idling.

Change your gearbox oil, and clean out the oil strainer.
Should help.

( On some models, you have to remove the gearbox oil pan to clean the strainer )
