Oh, wow- I'll look into that. However, we pulled the codes yesterday and it was showing an o2 sensor this time. My mechanic said the o2 sensor could create some sputtering. He also suggsted that we just wait a week or so to see if the sputtering goes away- apparently when he changed out the gasket there was a small amount of oil that had stayed in the chamber where the spark plug sits (?). Dont know if I repeated that correctly.
I guess I'll see what happens over the next few days, but I will mention it to him about the fuel pump.
Thanks again and Happy Holidays!!!
