Not sure if this is where I post, but I was driving to work, and went to get on the on ramp, and I noticed that my engine did not down shift or rev at all to get up to speed. Floored the pedal and it barely made a difference. Its a 94 4 runner V6 SR5 with 185kmiles. Only other thing I noticed recently was a few turnovers to get it to start but always starts and no rough idling or any weird noises. No check engine lights. The vehicle is new to me, 3 weeks, and not sure if the exhaust is supposed to smell gassy or not on this vehicle. Any advice?
