0608-Cylinder 1 misfire

0401-intake air temp sensor

0503-upstream o2 sensor

Where do i start, this just happen has i was driving to get my lowering springs and stillen kit install, so i pulled over just the codes and reset the ecu the codes cel hasn't come back on just but still drives like ****.
So what do i do

Check your ignition coil on cylinder 1. it may be bad and that would cause your car to misfire and run like ****. make sure your intake temp sensor is plugged in tight, I had that code and i just unplugged it and plugged it back in and reset the ecu and it went away.

 

So just swap out cyl 1 and 3 to see if the code moves

 

you can do that or it has been suggested the procedure is checking for continuity with an ohm meter. I just posted a question about the procedure myself. I am getting the code for ignition signal circuit so it doesn't even tell me which cylinder.

 

btw, if you need a coil I have a few for sale.

 

Anybody else????

i have had my share of problems in these past couple of weeks... ive had codes come up for
-knock sensor
-engine coolant temperature sensor
-crankshaft position sensor
...i have fixed the engine coolant temperature sensor, i bought a new one at the dealer which was surprisingly cheap... they also told me not to worry about the knock sensor, many maximas they said have faulty codes that give out 0304, which is the code for the knock sensor or circuit fault. i have yet to fix the crankshaft position sensor though
