GSI - Bad Fuel Eco

[CaP]

hi,
can anyone help me with this Q's
after my service - my car fuel eco has become bad, from cold start my rpms starts @ 1,700 and then drops until 900ish, but on Drive the car is @ 750 mark, which is normal

i was getting 400kms per tank / its at 200-250 atm - normal driving / freeway
what i did recently the service was, castrol oil, oil filter and Spark plus ( ZFR5FIX-11 )
Honda Integra Gsi - 97 model auto

would resetting the ECU (ECM) ? will this fix the problem ?

is this how it done

step 1: take your car for a drive to get the motor to operating temperature.
step 2: take your car home, and take the fuse for the ecu out. . wait 15 minutes.
step 3: put the fuse back in.
step 4: turn the car on. DO NOT TOUCH ANYTHING. GIVE IT NO GAS. let the car idle for roughly 15 minutes, or until the car is idling smooth at lower rpm's.
step 5: turn the ignition off. ONCE AGAIN, DO NOT TOUCH ANYTHING OTHER THAN THE KEY. immediately turn the ignition back on after you have gone to full off. this will store the new settings your ecu has made.
These steps will properly reset your ecu. After they are accomplished go do whatever, the new settings have been stored.

what weight oil are you using? the heavier the weight the more stress on the motor = bad fuel millage.

how do you get 560km from a 50litre tank ? when does the petrol light come on?
i get 375km wen my light goes on. then can push another 75kms and wen i refill i pour in around 46 litres.

oil grade is 5w -30, i cleaned my iacv - would this cause more air into my intake - to mix with fuel?
before service, 10L per 100kms
[after service with problem (before ecu reset - 20L per 100kms .. ) waiting for results over the next week
