Here is the most common cause of this stall, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

My 2000 cadillac sts won't do nothing but crank up


have the fuel pressure checked with a gage as if its the fuel pump not functioning properly can cause this problem. also if you have anti-theft on the car it may have activated for some reason and needs to be reset.

I need the radio security code for a 1999 cadillac sts


You will need to contact Cadillac service at your local dealership. Give them the serial number on the radio. They can then pull the anti theft lock code from their companies archive. The serial number on the radio is typically tied to a VIN, but since you bought just the part, they can't search that way. Hope that helps.

I have 67k on my sts and im hearing what sounds like a sloppy timing chain chattering from the right side of the engine as im sitting in the drivers seat. Im aware that there are 3 chains in this motor and...


Yes, it is possible. Most probable cause is a timing chain guide that is broken or the hydraulic chain tensioner is bad. No way to tell without going into engine. Unfortunately Northstars are not fun for the novice, or even slightly motivated weekend mechanic to tackle.

I live in Las Vegas Nevada and it gets pretty hot Blazer dies out


I do not know what year your truck is but I would remove the ignition module from inside the distributer and remove the rotor so you would have access to the module. Take the module to oreillys and have them test it. Sometimes they make the car act like the car is running out of gas.
