OK so I own a 2006 Cadillac CTS 3.8 automatic. It has 115 thousand miles. I was out driving the other day and first my traction light came on and stayed on along with the service airbag light. The airbag light would come on and go off. I pulled over shut off the car and started back the traction light went off but the airbag light was doing the same. So I went on to the store parked it and done my shopping. 40 mins later came out to start the car and it started fine however after doing so the airbag light of course was still doing the same only this time the security light was on as well. Yes it has the smart key of course. However it is the factory key not a remade. Started it the next day and the security light is no longer on however the airbag light still is. The car has recently before I bought it had a new battery put in. This is less than a year old so I don't think its a battery issue. The car does say when it's running that its chariging between 13.4 to 15.4 volts it bounces around like crazy. I've tested with a multimeter and seems to be accurate. My biggest question is do you think this is an early sighn the PCM is going ? I have also scanned with no codes found. My other question is I recentally changed the spark plugs and had to remove the intake to do so. I replaced the gaskets for it and tourqed to the proper specifactions. Upon removing of course I found sludge in the intake ports. I cleaned most of it out with a soft bristle automotive brush. I seen that it was collecting in the intake just after the airbox. Would it be wise to add a catch can on the intake? Also I seen where you did the test with the new product on the vw jetta 5 days ago. Do you recommend that product for my Cadillac as I have been a huge user of seafoam. Thanks for doing what you do and being there for the public. I'd love to bring my Cadillac to you and let you give it a good look over. I'm so glad you moved to Tennessee and I'm sure with the things going on in tx now so are you. I hope you don't have any family down there and hope your staying safe. Thanks agian and god bless.
