Hey people, got a my99 classic and it has a on/off feeling under WOT on full boost. Cant really notice in in lower gears, its noticable in 4th and 5th, genrally starts around 5ooorpm. It was running fine till i changed the oil and overfilled it slightly and i now have this problem. Ive now drained the oil and i still have the same problem? Any suggestions? Havent reset ecu yet or done boost solenoid clean is that first port of call? Just seems very odd? Car is fine if full throttle isnt applied its jus on WOT?
Cheers

my way forward would be to reset the ecu.. if the idle is then unstable then replace the MAF sensor.. if idle is fine then change the plugs...
