2003 zo6 missfire problem
got a problem with zo6
left home and got a mile away and the motor started running rough
won't idle and popping noise from motor
had engine light on
with scan it said engine missfire
cleared code
then map sensor code
replaced sensor and cleared code and still does not run properly
and no more codes came up
with scanner it seems o2 sensors and working properly
seems it is only running on 4 cyl
awfull smell from exhaust as well
one other thing i can hear a ticking noise from front of motor
almost like a plug wife is off kinda ticking noise
anyone have a clue what i can look for to solve the problem???

you never told me if you checked the plugs or not. You said the battery was new...check and see if the connections are tight. i dont understand what you mean by guage says its still charging...clarify. im no guru, im just trying to help a fellow vette enthusiast

no never checked plugs
did not think 3 or 4 plugs would go bad at the same time
i was driving it when all this started
i feel the exhaust ports are i think there are 3 or 4 that are not firing
they are cold and some are hot
before this happend i could hear a ticking noise from front of motor
faint and i thought it was a bad belt maybe
today i will pull the plugs and see

I had this problem and it turns out my o2 sensors were crossed and the intake valve on the 8th cylinder made contact with the piston. I say pull your valve covers and check your springs first because that ticking noise is not normal. I threw a map code also. PM me if you have any other questions

ok new plugs and wires i will pick up tomorrow
thinking i weill take it in to an expert and have him look at it
what i don't get is i was driving at 20kms on a gravel road when this all started
barely off idle in 3rd gear
and the road is rough so i go slow
i keep thinking something came unplugged or corroded connection
hope its not valves
