mis fire 0n cyl #4
 

i have a random miss fire on cylinder #4, replaced plugs and swapped coil and still having same issue. by the it is on my hot rod. 2000 chevy metro 1.3l. lol i know but it gets good gas milege, but i do have this issue. also have a code also for cam sensor, which it is not a random miss fire. any clue

I thought the metro 1.3L was a 3cyl?

nope 1.3 is the 4 cyl. 1.0 I believe is the 3 cyl. my friend has 2 (well, swift gt's) and his whole family owns them. yes they are a gas saving family lol

as for your problem, have you noticed any loss in gas mileage? may have a leaking injector. 200o has coilpack correct? if not check the cap for signs of carbon tracking or burnt contacts

swapped coils but still have same issue, but not injector
