I recently replaced the throttle body and that fixed a small problem i had. But since i bought the car every few months i get a p0300 code and then it goes away by itself and recently it came back and now its always pending so it comes and goes. But car runs perfect idles great and never misfires, whats the problem?

Recently changed intake manifold gasket and elbow gasket and throttle body gasket and newer throttle body.

Since i had to reset the ECU to perform the idle relearn i also noticed my readiness monitors for catalyst and o2 sensor are still "incomplete" or "not ready", Its been 250 miles since i did ECU reset, why are they still not ready?

*EDIT* the car just set readiness, it took about 250 miles and 8 days, no explanation it just did.

Car runs perfect, i dunno if i should do anything.

O2 sensor - dont know, my fuel trims are nice and good

Maybe... Depends on how you loook at it

If you do replace the coil packs... GO OEM!

DO NOT LISTEN TO George_ I bet you have a aftermarket coil pack in there! its one of the issues with using non oem.

A miracle just happened my car set readiness it took 8 days everything is ready, cant believe it took so long but that worked out.
Ok ill look at all the coils and see which one looks different
