#1085 of 1217 Rough Running Catera by tholtz Jun 16, 2009 (4:48 am)
Could use some help with the newest problem with my Catera. Just started running poorly yesterday it does not stall but it has very little power, and acceleration seams to be a real strain on it. Once up to 55 it smooths a little, but when parked smells hot like something burning not a normal odor. I can hold my hand over the tail pipe and feel the engine miss. Question do the converters go out often on Cateras or is there somthing else I should look for? What codes are common if I can get it scanned? O2 sensor's maby? I also have to replace the heater core now that I see it leaking from the firewall how big of a job is that, not much from the dealer on this car they hate it.

Replying to: tholtz (Jun 16, 2009 4:48 am) The converters go out after 90K or so and a flow test (drilling a hole prior to and after the converter) should confirm this. The before and after sensors are also commonly replaced. Your looking at 2 grand at the dealer. Absolutely try to use a muffler shop.   Codes would include misfires and many others.   I would rule out the heater control valve prior to replacing the heater core.   How many miles do you have on the Catera?

Replying to: cateragirl22 (Jun 15, 2009 7:19 pm) Cabin air filter could be the flooding problem or maybe you have a bad heater control valve. I paid $150 plus tax for a mass air flow, its a snap to install.
#1088 of 1217 2000 Catera, No radio, No heated Seats, No AC, Whats going on!? by jared0029 Jun 22, 2009 (11:32 am)
I have been searching all over and can't seem to come up with a direct answer. Please help me.   I have a 2000 Cadillac Catera. The radio does not work, it only comes on when the car is off. At the same time that went out, the heated seats did as well. Does anyone know what the problem is here?   In addition, when I turn on the air conditioner, the oil pressure drops below the red when idling, and only shows pressure when accelerating. Also, when the ac is turned on, the temp gauge gradually climbs up into the red.   I would appreciate any help. Thank you.

Replying to: jared0029 (Jun 22, 2009 11:32 am) radio does not work   there is a little gray box on the drivers side, forget what they call it, but you need a new one.      > Started since 2 days ago.

Remove the black vinyl covered insert that is underneath that. With a flashlight, lay on your back head next to the pedals and look up and to the right, over by the fender. Gray box just above smaller red box. Twist the gray box slightly clockwise and pull up. It should pop off it's mount. Now remove the wiring harness plug.   the oil pressure drops below the red when idling, and only shows pressure when accelerating. Also, when the ac is turned on, the temp gauge gradually climbs up into the red.   Is the coolant the right mix of half water and half anti-freeze?

Replying to: jared0029 (Jun 22, 2009 11:32 am) My 2000 is the same way. The oil pressure goes way down when it gets hot. My AC don't work so it won't pull it down but the low oil pressure is common on these cars. I don't know what you can do . I was thinking about useing a 5/20 oil. My car radio comes on when it wants to and goes off when it wants to. When I first got it the radio only came on when the car was off and I changed a bad fuse and it worked. I would be careful about the heated seats because , from what i hear, they catch on fire. My car smells hot to but the gauge doesn't show it. You would be well severed to read all the old post on this site. Are all your engine fans working and maybe you could take out your thermostat like we did years ago so a car wouldn't overheat but then you need to put it back in for winter.
