I bought a 1997 Bonneville SSE. Recently i have been having some problems. The car gets jerky and sometimes dies at random,when it does the gauges go all go back and forth and it sputters really bad, bot only sometimes. I ran DTCs it gave a several codes, i replaced MAF sensor, and it didn't help, replace catalytic converter, and it didn't help, i cant drive car to get codes read again with it doing this, so i was hoping for some suggestions

i had a similar issue with my 97 ssei my battery cable refuses to stay tight and i got an maf code as well i took my maf out cleaned it out with compressed air and replaced my plugs wires and alternator and shes just fine now except for the battery cable thing it may not be whats wrong with yours just an idea i guess also make sure your tranny fluid is overfull because mine was and it made my car shutter

****correction is not over full*******

Ill give it a try and let you know how it works out. thanks

I would start with checking and cleaning the battery cables. Sometimes they get loose or corroded and can cause the engine to cut out.

i agree as mine refuses to stay tight when i hit a big bump my cars interior electral does what it does when you turn the key on so yeah that would be the first and easiest thing to check dont forget check both ends of both cables not just where it connects to the battery

How about giving us the codes you had. While many things are clear cut..sometimes the codes point to different stuff that you'd never instinctively look at.

as soon as i can get codes ill post them to see what you think, thanks
