Hey Jay,
The pop, pop, pop, at idle is normal. Mixture is pretty rich at that point
in time, especially if it just came down to idle from higher RPMs.

Hi Ron
Thanks for getting back to me.
At idle and when I'm accelerating the tach seems to jump up and down slowly.
The IAC is fine and there is no gas smell coming out the exhaust pipe, but
when I put my ear to it (exhaust pipe) at idle there is slight pop, pop,
popping noise. If I do the computer on off 3 times to check the codes would
a misfire be detected? I've tried and all I get is a 12 & 55 which are
normal.
Thanks again
Jay
