CEL popped up today on my way home from work. When I got home I checked the code and its 72 and 73. Gonna try and find out what the problem is tommorow. Damn it and the car was running fine for such a long time too.

according to those codes, your 2nd and 3rd cylinder are misfiring.

I know what the codes are just gotta figure out why they are misfiring.

maybe fouled spark plugs?

I just changed the plugs, distrib cap, rotor, and did a oil change and adjusted my valves and reset the ecu. All better Been needing a tune up so I guess the cel just made me get off my ***. Had to drive the celica around for a while! Hehe...vvtl-i ownz i-vtec! j/k

do you have the GReddy Blue box?

The fmu setup.

check injectors, the o ring all the good fuel stuff. very easy to get a misfire with fuel being distributed improperly. just troubleshoot it .. good luck
