Went to go look at a 94' SC 97,000 miles 40,000 on new motor. Took it for a test drive and when i tried to give it gas, the motor would cutout, the accleration was real jerky and the boost gauge was all over the place like going up to 10-12 pSi and jumping back down into Vac readings. I couldnt get it over 35mph. This car sat for the past year the owner said, and she said it didnt do that before. Just wondering what could be some causes of this. (Bad fuel, spark?, anything major) Any help is appreciated.
 
Old gasoline can be the culprit.
If your running old gas its going to be a bowser.
You may need to consider fuel system matainance to get er go'in

1-get rid of the old fuel
2-new filter
3-have the injectors cleaned
4-make sure a chipmunk is not living in the air intake :eek:
 
When we bought my brother's 93, it had sat for a long time as well. It ran rough for a few seconds, then fine until weeks later when it began acting up again. Same symptoms turned out to be a bad DIS.
