This is what my 2000 Catera is doing, and i've talked to alot of Cadillac specialists and they say it's the Transmission Control Module. Reason being, is because my transmission won't kick in to a higher gear while these lights are one... It shifts just fine, but for instance if you floor it, it won't kick up, it strips... Mechanic and Cadilla dealer say because of that, it's the TCM...
Anyone else experiencing the tranny shift problem while these lights are on?

jak6 there is no cap, there is a coil behind the engine on drivers side. you do not have to pull the top of the motor. on the drivers side there is case that holds vacum lines & wires unbolt that & you can get to the spark plugs on that side. pull your wires & start removeing plugs. you need to know the fireing order on motor & coil. Sence i have a 98 catera i know it. on the motor driver side starting from the front is 2,4,6 passenger side is 1,3,5. Now on the coil starting the front row from drivers side to passenger side is 4,6,2 the back row is 1,3,5. What cylinder is not fireing i just had the same prob with mine & it was cylinders 2,& 6. If you have any other ? I can help.
#1005 of 1431 coil and distributor location

Can anybody tell me the location of the coil and distributor in my 1997 catera?

Coil is buried between firewall and center of back of engine. Distribution of firing plugs sequence is computer controlled, no distributor like older model cars..

Could the computer be missed programed to not fire on one plug or is coil bad thank for any help

I've got the same problem, I've done a spark test on that cyl. and it's firing. Note: two plugs fire at the same time on every stroke according to the factory manual.
I had a service station check fuel injectors which were OK, A mistake to take everything off to take it in to the station for a check. I now have no compression on #4 cyl. Which tells me I've either got a burnt valve, stuck lifter, or stuck valve which would hit the piston being stuck open.
Best to pay the $90+ for analyzation by a pro. These cars are setup so analyzing tells it all. You could check wires and plug yourself first.

There are some really sharp mechanics on this forum. If you go thru the previous discussions you might find more clues. You can search for (ECM) for instance.
It seems that I saw something before about the ECM shutting off a cyl and also if some other sensor is defective it will gradually affect runability. For instance the crank and cam sensors are known to go bad, especially crank. So you could search for (crank sensor) and it will tell you how to change it. These are Opel engines and most mechanics don't know their quirks. They are a superb car once you iron out the bugs. Some were used as police cars in Germany.
#1011 of 1431 2000 Cadillac Catera Rear Brake Lights

I own a 2000 Cadillac Catera and my rear brake lights will not shut off when I turn off the car. It's drains my battery dead.

Search forums for expert advice.
I would think it's a pressure switch in brake system, older cars had this prob. occasionally and either it would be air in the line causing pressure or the pedal switch under the dash not releasing switch button by being out of adjustment.
But with this highly sophisticated brake system I wouldn't bet on those issues being the answer.
