Engine Performance problem
1993 Pontiac Sunbird 4 cyl Two Wheel Drive Automatic
My problem is that my car is cutting out. I have had the injectors looked at, and was told nothing was wrong with them. The last time I put gas in my car, I put in super and it seemed to help quite a bit. What else could be wrong?
How long since a tune-up? Are there any applicable trouble codes? Use a gage and check fuel pressure. Some of the national brand auto stores used to loan out a fuel pressure gage, if you don't have one. Does it cut-out at idle or running down the highway?

It cuts out when running down the road. We just had the injectors cleaned and it seemed to help, but we may need a complete tune up.
