Vaccum leak or bad gas!
The cadillac catera did not come out with a key for the trunk its all electronic so if your battery is dead there is a release lever in the trunk on the trunk lid.
Oil dipstick is in the regular spot for most cars trans. The catera did not come with one it is checked under the car
There are several different vehicles that come with the 4L30E transmission. Some of these vehicles include BMW 3, Isuzu Rodeo, and Cadillac Catera.
Sounds like an overcharging alternator. Check your voltage, It should be around 12.7 - 14.5.
It's adjusting to the weight of cargo in your car it should come on when first started if it stays on there is a problem with your rear air suspension =/
Have the problem that caused the check engine light to come on repaired. They will reset the light with an OBD2 scan tool. The light will just come back on if the problem is not repaired.
The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
I'd start with the crankshaft position sensor cheap fix (50-60) bucks & easy to install if that doesn't work come back and update i hope this helps
Ensure the light is switched to come on only if door open.
There are thousands of 1999 Cadillacs on the popular bidding website eBay. The vehicles range from Escalades to Sevilles and come in varying conditions and prices.
Well I had problems with my radio working while the car is running and all I had to do is get a stronger fuse I think it was a 10 and we put a 20 and its been fine ever since.or if its a 20 put a 30 etc.
It depends, if it was idling you may get lucky. Most of the time it needs 4 new valves per cylinder and that means the heads have to come off. As much to fix as the car is worth usually.
