Over the weekend I had to pull off on the highway. I had to gun it to get back on and got to about 70-80 in what seemed like maybe 5 seconds, which obviously topped out some RPMs. The car has since sounded like a motorboat with a short timed repetitious stuttering sound. When I reached Benton Harbor and made my way down the offramp to Pipestone the car died at the stop sign. And subsequently every single time I've had to brake since. I've watched my oil pressure fluctuate wildly during the past day or two, all the way from 120 for a short while after I added a quart of oil, down to the red zone when I'm not applying gas. The car also dies out if left at idle.
Some of my precursory research shows that all of this might be related to the vacuum system having a leak and thus having to go way above and beyond to try and actuate the brakes which kills the rest of the system. Another option showed the Torque Converter Clutch or TCC Solenoid could possibly be at fault, improperly disengaging/engaging the transmission from stop & go duties. Additionally, the odd new sound has my mom suggesting the unthinkable of a thrown rod.
have the same problem?
