fist take a look at the sparks. the blacker they are, the weaker is the lambda maybe. this is important fpr FE.
if everything is ok so far, open the black lid over the air flow meter. u will see the spiral spring. and under the stuff a saw blade like gear. release the hook holding it and tigten the spring. so it will signal less air and the injection will add less fuel.
if u wanna be sure, connect a cheap AFR gauge onto the lambdasonde. in open loop it will show what happens. even a simple voltmeter will show u whats going on...
