So I told her that maybe the SI-1 will help, but so far, it has been 100 miles since adding the SI-1 and nothing has improved.
Hmmm, maybe it needs some GM top end cleaner or something? Cleaning the MAF would do it some good as well.
Totally different car but the 2000 Corolla in my sig was having a hesitation/low power issue. I cleaned the MAF, replaced the air filter, plugs, pcv valve, etc. Only thing that made it go away was 2 ARX cycles, so it may have been a compression issue or? Now we have all 125 Horses of fury
Anyways, I bet that low mileage Corolla is pretty clean so that shouldn't be the issue, I would try the MAF and top cleaner first, maybe even another bottle of SI-1 or Regane, Amsoil PI, etc.
Good luck!
