Replying to: jak6 (Mar 22, 2009 7:04 pm) 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. Dave |

Replying to: jak6 (Mar 23, 2009 3:57 am) 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. Dave |

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.

Replying to: luggie34 (Mar 23, 2009 9:07 am) 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. Dave |

MY 1999 CATERA WILL START, BUT WILL NOT ACCELERRATE. The car acts as if the gas pedal cable is not connected, however, I understand there is none. My mechanic said that I either need a new main computer or an accelerator sensor, but he is not sure. he said it would cost to much for him to just guess and the cadillac dealer is not any help, beause they say they don't know what is wrong even when he gives them the codes. They obviously want him to have to send the car to them. at any rate, i was just wondering if anyone can help. Maybe it is the main computer, but I would like to know before I buy one. The car starts fine but just doesn't move, as if it is not getting any gas. I don't hear any indication that the engine is getting gas no matter how far I press the gas pedal.
