Hi :right:

any person with this problem soulution, Pls, HELP ME :liebe011:

run the car when standing and raise and lower the revs ie: 1000-3000 and see if the engine stops picking up power then regains it, or shakes at any point.
it sounds like you might have a problem with a damp spot.
check to see if any mods have bean done the the air system.
put fuel cleaner through it
check ht leads and plugs

Thanks wolfendrac, :thumbsup:
