Ok, i forgot you just bought this car, they are supposed to pay for all the repair , you have for sure at least 1 month full warranty.(the dealer/seller warranty) and your aftermarket warranty . If im not wrong.

Man, I hope so, I cant help but think it would be a bad way to start this new relationship by shelling out 500 bucks before even owning it a week, lol. I'm taking back in the morning, so I'll let you guys know what they find.

UPDATE: Well, took the car to the dealer and it did turn out to be the pressure sensor/solenoid, they said it would've been a ~$700 repair to fix, but they will fix it for free since I havent owned the car for even a week now. Boy, am I glad I didnt wait around to see if it ever happened again! Good call Mike on the diagnosis, hopefully this will be the last of my troubles with my new (new to me) Bonnie for a while. Thanks again fellas.

Good to see you will have it repair for free, once i have my bonneville i had practicaly all common problem available for the bonneville ,but some here never had any.

But one thing is sure, i love this car anyway. despite all the problem i had.
Those car are simply unique.

Cheers
