Having trouble with the new JDM Levin, when I was buying it the 1st thing I noticed was that it was well down on power. I didnt buy her to wreck her so I just thought, Powers steering, Aircon & cat converter are prob sapping most of the power but its starting to annoy me.
Heres the symptoms, no power off the line, rev to 4-5000 release the clutch & the car drops to about 800rpm before slowly picking up, goes fairly well above 4000 rpm. The car is unable to complete a dounut from a 6-7000 start.
So far, I have checked the timing, used injector cleaner, cleaned the air filter, changed the plugs, removed the cat converter.
Did notice a touch of oil on the dizzy tonight but I will attend to that.
It drives like a car that has big cams except it has standard ecu & pulleys it idles/runs like a standard lump.
Whats next,
Check the fuel pressure, check the injectors, check for a vacuum leak (cant see one).
Compression test even though there is no smoke & it drives well.
Stick an F20c in as if
