97 Camry V6 misfire
I own a 1997 Camry V6 with 260,000 miles, recently it has thrown an engine check light code (, P0300 Random misfire & P0303 misfire @ cylindar # 3) and the engine was hesitating at the time.
I related the problem to a bad fuel as I ended up resetting the engine light and added Techron (injector cleaner) into the gas tank and within a mile the hesitation was gone and stayed so for 4000 miles.
The issue re-surfaced again yesterday within 15 miles of filling up the gas tank, I did the same thing and the issue was gone, reset the light and I was good for about 60 miles untill this morning in which it came back again along with hesitation and I am suspecting a bad injector at cylindar # 3 specially that the wires, spark blugs are new (15,000 miles on them) and even after I swapped the coiles the issue perssited at the same cylindar.
Any ideas what I should be looking into in order to trouble shoot this problem ??
