Hello. A last few months i have a check engine light and i cant find where is the problem. After diagnostic ive got P1113 - powertrain code and it doesnt tell what exactly problem is. It just writes that its fuel and air metering problem. When you delete fault and ir comes after 2-3 seconds again. Maf sensor is good, egr cleaned, i checked intake manifold valves and it is also good. Car runs great, furl efficency also good. Only check engine light is on. Car is Honda Civic 1.7 cdti diesel 2004y
