I'll try to get it replaced this afternoon. Just drove it home from work and it acts like it has an air leak. But it did before I changed the SOV, but not as bad as now. Listen to this: Yesterday after replacing the SOV it ran poorly, groggy power and hesitation, idled fine though. Today going to work (40mi) ran great, thought maybe it was just some residual air last night. Both lunch and drive home its running poorly again, bad hesitation.
