2001 Corolla - rough idle on initial start up in the morning, then clears up, then hesitates slightly on accelleration from a dead stop after that.
I've changed coil packs, spark plugs, MAF & O2 (upstream) sensors, & added a fuel injector cleaner.
Still have idle & hesitation problems - help!
have the same problem?
