Misfire codes daily?? when I first got the car it threw a code, the guy got it cleared and it ran without a code for about a month. Friends with cammed LS1's said itll come on every month or so. Well I chaged out my TR55's for some TR6's in prepperation to spray. It ran better for a lil but then threw a code, cleared it, comes back. Now every 3-4 days i have to get the code cleared, it only appeares at idle. Could my plaugs be fouled allready due to not spraying on them, maybe wires, or a coil going out. Car was tuned after the cam install.
im having the same problem and i just changed my plugs to tr55's and i also got 8.5mm plugwires. so it defenately isnt the plugs or wires. i also have tryed running diferent ocane gas and it has no effect. for thoes who are not shure what code this is its code 300(multible missfires) mine also just happens @ idle. please let me know if you find out whats wrong with yours if noone knows whats wrong

bump back up since car still does it. I dont clear the code anymore since its so fequent. After driving for a while it goes off but comes back on later down the road. Only comes on at idle
