stumbling motor

[SHOSIG]

I am now having a problem with my SHO. It first seemed that whenever parked on an incline, when I went to restart the car.....the idle was very choppy and would stumble....drive the car into the garage and it would start fine the next day. While coming back from work, during part-throttle, the car started stumbling again and the CE light came on. Went to Autozone and they pulled a code 114(ACT sensor), I had an extra sensor so I installed it. Next day, car did the same thing. CE light comes on but does not store a code in the ECU. Any ideas? shrug

Sieger - Have you checked the fuel pressure?

No, my brother has my fuel pressure guage, but he is going to take my car to his shop tomorrow and run a bunch of diagnostic equip. on it to find the problem. I don't want to keep replacing parts guessing what the problem is.

I have a problem sort of like this too but I need to send my injectors in for a good cleaning and balancing. Got a spare set but I want them to be like new(or as new as I can get them wink )
Now to just find a place that's close that can do this...

Car is fixed, it was the DIS module. It would intermittently cut out cylinders while driving.

Unless the DIS was tested to be faulted, there is a chance that a loose or intermittent connection of one of the DIS connectors could have caused the same symptoms.

And this can be caused by worn out motor mounts or a failed SFB retainer!

New reinforced mounts and ALSFB were done this summer. It would stumble at idle also, not just driving.
