Is the car engine still sputtering and shaking?
The same sputtering and shaking that you report. My engine had only 28,000 miles on it at that time and now has 122,518 miles and runs smoothly and produces a bunch of power. I still enjoy owning it. 31 people found this helpful.
What to do when your engine is sputtering and losing power?
Be sure to check the rubber boot connectors for the vacuum where it connects to fuel pressure regulator and at throttle body and trans. Mine were all cracked and leaking and not obvious. All of the damage was on the bottom out of sight. I moved them and there it was. Replaced them and problem solved.
Why does my 1999 GTP engine keep sputtering?
My 1999 GTP experienced the sputtering problem at 28,000 miles and it was the result of a defective wiring harness. I assume this to be very unusual but it can be the cause. Best of luck. 30 people found this helpful.
