[loosthong]

Hey guys I'm a car noob with a rad rolla......but theres just somethin wrong with it, its a blacktop 20 valve in an ae92....

i got it a full servive after i bought it, but its running at about half its power and is using shit loads of fuel.

and its not the airlfow meter.

anyhelp would be awsome cheers

Explain "using shitloads of fuel".

Also explain "half power"

Both these terms are qualitative, not quantitative.

It should not be the air flow meter, because Blacktops are MAP sensored. You should have no AFM.

O2 sensor can send your fuel out. Map sensor leaky.

Are you running 98 RON fuel in it? Knock sensor can pull timing if it detects too much knock (low RON, dead sparkplugs, dead ignitor, many things.)

is it missfiring? if so check all ignition components and also injectors, fuel pressure etc... you say you are a car noob so you prob wont know if its an electrical miss or not.... if not could be blocked cat/ exhaust component... remove exhaust upstream of cat and go for a drive (somewhere cops arent!) so many possibilities need more info... best off for you to pay someone to look at it
