Incorrect installation of the chain. It is backfiring because the timing is off. Remove the chain and do it again correctly.
Time for a tune up.
its not your ignition its your crankshaft sensor that's the same problem i had.
the problem is that the starter is inside the engines of northstars, bad design, only good for cadillac service centers, real rip off cost between $2,000 and $3,000 to have replaced.
Try replacing the sparkplug. I had the same problem, I replaced the sparkplug and made sure the carburetor filter was clean. I also drained the gas tank and replaced it within new 93 octane gas. Hope this helps It should run perfect after that.
you still have a problem the light only comes on when it stores a current code
my car starts every now and again, but when it does start it turns off and then it backfires. i dont know if it is the fuel pump or the sparkplugs or both, please help me find the problem.
yes, study witchcraft, but i warn you, it backfires a lot.
I had a problem with my 97 deville air ride and the fuse in the trunk labeled RSS was missing so I replaced it and the shocks started working.
Have your front tires high speed balanced
Sounds like the brushes need to be replaced. Find a shop that can check your regulator, and who can rebuild your generator.
Cadillacs are notorious for blowing head gaskets. You may want to look into that.
