this weekend i replaced my intake manifold gaskets (both upper and lower). now my CEL is doing weird things. when i first cranked it after the change, there was no CEL on at all (YAY!). i needed to leave to go somewhere a little later and the CEL turned on solid. i just ignore it, but by the time i got to the end of my driveway, the CEL started flashing. i pulled back into the garage to take a look. i can't find anything wrong. anyone know what might cause this?
everything i've read online says misfire, but there is no reason it would misfire. i checked all of the injectors to make sure they were connected right.
