Misfire codes but no misfire???
I am getting multiple misfire codes, but the car runs perfect. P0300,301,302, 303 and 306. Its the 4.2. No misfire, no cold start issues, no hot issues, nothing. I just replaced the intake gaskets hoping that solved the problem but it did not. Whats weird is the car runs fine, and i can clear the codes and it takes about 200 miles for them to come back. It need to get it smogged but i cant till the codes are gone.
Any ideas?????

+1 to Amadauss - additionally, check the condition of your battery (outside shot) - I would also check to ensure the fuel injector electrical connectors on all 8 injectors are tight and snug - finally, misfire codes could be so intermittient that you are not "feeling" them (cause they are "balancing"' themselves out) but causing the CEL to light up - get a COP (coil on plug) tester and test each coil at idle.

Its an 05 with 200k on it, i just got it as part of a trade. I replaced the lower intake gaskets and both water pumps. I removed the plugs and they looked okay, but i know that does not mean much. I understand the historic codes, but the smog ***** in california don't. The computer must been clean and have run all self tests to pass.
