I purchased the intense pkg 1. I have everything installed except for the pulley and spark plugs. If I install the spark plugs first is it going to make the car act like it'* misfiring? THanks

Which plugs come with the level 1 kit?

autolite 605'*

I'd do them at the same time as the pulley. Only takes 10 min.

Well, now I have already swapped out the plugs and the car is fine until the boost meter gets close to 0. I had intentions of doing them at the same time, but I had something I had to go do and had to drive it. Do I have a bad plug, or would this be normal?

Change the pulley and see if the plugs fouled.

if the problem exists after swappin in the new plugs I'd pull each of them and check them....also reseat all the wires to make sure they are tight.

The thing is.. the plugs are at least one heat range colder. The pulley and plugs need to match.

That is what I thought, I'm hoping that takes care of it...Me changing the pulley....thanks

ok, so I put the pulley on today. Still had the misfire, took it to autozone to read the CEL. Misfire #5, Put in another Autolite 605. Operated much better, but not perfect. Once you get arourd 5psi the motor goes nuts with misfiring. So I took it to Advanced autoparts (because autozone can't clear cel codes). Cleared to code and went for a drive to get the light to come back on to see what the problem was, came back "Random Cylinder Misfire" ??? Any suggestions?
