I tested it with fresh 98 octane . but ive have never changed the fuel filter since ive bought it maybe its blocked ?
yes it feels like youve taken your foot off the pedal when your full throttle its very weird . i have disconnected the plug and then tried starting it but wont start without accelerating and wont idle when it starts so it should be okay . i might try making a test pipe to see if its the cat thats blocked . This just happened out of nowhere car was running so good where ive dyno'd it only a couple of months ago and made 107 kwatw .
