Multiple Error Codes
i had an error code of p2004 on my 05 expedition. we changed out the intake manifild runner control. that error went completely away but now i have 3 other errors showing up with check engine lit up. i have P0171 (bank 1 combustion too lean), P0113 (intake air temp sensor 1 circuit high input) and P0202 (Cylinder 2 injector circuit malfunction). We changed out cylinder 2 fuel injector. the engine was real rough like when a coil pack goes. so we changed out a new spark plug and coil pack. now everything seems to run fine but the check engine stays lit and the same error codes are still there. i also changed out air filter. what do you think the problem is? im scared to think the intake manifold has to come off again. that was an all day job.

P0202 usually means the injector isn't properly plugged in, check the connector and make sure it's making a good connection. P0171 is probably related to the injector that isn't working. P0113, if I'm not mistaken, the intake air temp sensor is integrated in the MAF sensor. Check the connector going to the MAF and make sure all the wires are making good contact.
