My cadillac catera won't idle after it gets warm

ignition coil

It should be on the rear passenger side of the engine.

heres one of scotty kilmers how to videos to on performing this, you can decide after watching if you are up to the job . GL :)

• This is normal. On your car, on a cold start the pressure will be around 75 PSI. After the engine warms an oil pressure of 15-20 PSI at idle is just what it should be. The oil pressure gauge should escalate when accelerating up a bit to. If your old school like me 15 PSI mean danger but tat Caddy is just fine.

most likely a failed crank or cam sensor. Without testing its just a guess.

it's the cps (crankshaft position sensor)
it cuts off the power to the fuel pump as a preventive mesure, it's a very common problems with the catera
i had the same problem with my 2000 model

Did you have battery disconnected or dead recently?

Try to place ignition in run without starting engine for 3 minutes (shut off all accessories and lights etc..). Then shut it off and then start it. Should relearn the idle.

If this doesn't fix the problem, unplug the MAF sensor, if it runs fine with it unplugged, its the MAF sensor.

Exactly what happened on my wife's 01'.

if it is a north star it probably needs intake manifold replaced

Heater control valve is most likely issue for the first, other issues could be ignition related.
