well i recently replace new spark plug ,wire coil and starter it been running alot better than before and it wouldnt dying on me at a stop yet ahah, the funny thing is if iam crusing around the city with 30 mph, my idle will be shaky and the idle arrow keep go down to 500 and up back to 1000 and idle at 6 or 700 when i at a stop, but when i drive like 75 mph for like 25 minute drive i realise the idle is above 1000 and it dont shake at all or not as much,.. anybody have this problem lol????

 

A redline a day, keeps the carbon away.
Rotary engines like to be driven hard. Granny driving, in an attempt to save gas, will allow carbon to build up.
