Random Cylinder Missfire Code Everything is stock except for my cam and exhaust. The cam swap was very recent and it has been tuned. Started throwing Random Cylinder Missfire so I find a loose spark plug and wire. Tighten them and code goes away. Drive it for a couple of days no problems and sitting in traffic one night Check engine light comes on again, same code. What could it be this time?

That sounds reasonable I guess, but would the code re-set after the car has been turned off and cranked again?

thats the problem. yes it will reset itself if the problem doesnt happen within a certain amount of time. i have had the same thing for about 3 years now. if it shows a specific cylnder then i would worry. and it looks like your coming pretty close to your piston with that much lift on the exhaust i always heard .600 was about max with out cutting the pistons

Patrick G. spec'd the cam for me so I hope it is ok. I don't think he would have spec'd me a cam based on the info I gave him that would not work. Thanks for the help.
