Car runs great with only 100,000 miles on it for about an hour or so till it starts sputtering like running out of gas, then dies. After 30 minutes the car restarts fine and runs fine again for another...


I'v got one with over 301,000 miles on it. IT sounds like you need to replace the crank sensor. The balancer will have to be removed for that. Next time it stops running spray or pour some water on the crank sensor and see if it will crank. Did that to mine and it started right up until it got hot again.

Injectors shouldn't effect each other
You may have a bad coolant temp sensor, and it doesn't go into closed loop.
That is when it is warm and the O2 Sensors control the injector timing.
A bad thermostat also

Loosing power at cruising speed


Hi. I have two Dynasty LE cars, (a 91 and a 93). Both have the 3.3 litre. The 1991 had almost the same problem as yours except it would only do it once the engine warmed up, (similar to your freeway issue, given distance and time for the engine to warm up to operating temp.) I had it in about three shops before the dealer found an intermittent fault with the cam and crank sensors. I replaced them and now it runs just fine. I hope this helps.
