My recently purchased '97 FJX80 with 106,000 is a little hesitant to start - hot weather here now. The car seems 100% in all respects but to start the engine I need hold the key for it to turn over 3 or 4 times before it starts OR I need give a little gas pedal and it it will start on the first turn. Is this normal, significat. indicative of a problem?
