I just rebuilt my once cam ka and it still runs like shit. It has a hard cold start, and the idle is rough until it warms up, it idles anywhere from 800 to 2500 rpms, it also backfires while idleing and driving. When I press the gas pedal it lags until 2500rpms. I can feel a major loss of power when it drives, it's really sluggish. I checked the ignition timing and the timing chain and gears and there are fine. I've checked all vacuum lines, removed the egr. I replaced the spark plugs, wires and coil, along with a new tps and mafs. The only code im throwing is a code 13(engine temp sensor) I don't know if that could do it. This damn 240 is being a bastard HELP ME!!!!:bbb: :bbb: :bbb: :bbb: Im going crazy
