I have a rebuilt Y8 that has maybe 5k miles. Ever since its been rebuilt, at idle it would have a really rough idle. It would idle at about 9-1k rpms and then it would drop to 4-500 and almost die. Then after a few seconds it would pick up and idle normal. I thought that i had adjusted the valves wrong so i double checked the timing and adjusted the valves again even though they were good already. When i adjusted the valves i pulled the plugs and they where white like they had been running lean for a while. What also leads me to think that it is running lean is that when i let off the gas to shift it makes a ping/knock type sound and also when i hold the gas pedal steady and im not accelerating or decelerating.
The car has I/H/E and also a walbro 255 and thats all that it has done to it. The fuel pump is new and has a new fuel filter. Accasionaly it will throw a CEL that says Misfire on bank 1.
