So this issue just came out of nowhere. But First, my vehicle is a 2003 Cadillac CTS with the 3.2L V6. Ok, so I was driving to work this morning and I had my cruise control set. My motor started to jerk and it felt like I lost power for a moment and it was hesitating pretty bad. Only did it for a few seconds then stopped. Car sat for 8 hours while I worked. On my way home it started doing it again. But this time it was way more frequent. I check the fluids and the coolant and oil where at there optimal levels. No smoke was coming from under the hood or out of the exhaust. There is no major unusual noises coming from the motor either. But I have the issue of the motor jerking when I hit the gas and sometimes at idle. It will jerk for a few seconds then run fine then jerk and so on. Everytime it starts jerking the car has no power. When it stops, it's as if the motor is perfect again. If there is any tips or ideas to check for I would greatly appreciate any advice as this is my daily transportation to work. And if anyone has further questions that would help I will do my best to answer them. Again Thank you for any suggestions.
It all depends where you're living. We're having very coold weather now. How about some water/ice in your gaz line? Before doing anything else, I'd put one or two small bottle of gaz line anti freeze in the thank. It cost next to nothing and it may do the job.
what does your tachometer do during the power surges?
1. if the RPMs are going up during the loss of power and go down during the jerking than it could be torque converter and/or transmission related.
2. if the RPMs are dropping during the loss of power and go up with the jerking, than it could something engine related, probably electrical
have you checked for codes? it can be done without any special equipment on 2003 CTS
Your post has nothing to do with dealership service questions or original warranty work. Moved to the proper CTS forum.
Sorry. I'm new to the site.
And thank you for the two who actually responded to my question. I actually found the problem. I had a leaking gasket on the passenger side coil so all the ports were full of water. Replaced coils and all new plugs. Runs like a champ again.
