Hi, i own a 93 GSX (43K m)in stock conditions. I love the car and I am the only ony one allowed to mess with tha car's mechanics (no shops or mechanics can touch it) OK,I know...but where I live we have no emition control rules as you have and still better virtuallyno speed limit!. The symtoms are that at low rpm (2K-3K)the engine feels like somebody is taking the power out of it and sudently there is a burst of powerand everyting is back to normal. This change goes with the rpm increase and not with throttle position. Is feels like the spark timing were retarded and, without any logic reason the timing goes back to normal advance??. It keeps doing this all the time, it is not a big deal but something is not working propperly.Any help will be appreciated. <edited><editID>Rudy</editID><editDate>38089.5300347222</editDate></edited>
