my car just started doing this,at idle up to 2,000 maybe 2.500 rpms,engine shakes and vibrates bad maybe a miss to,but above 2,000 or so engine smooths out,i have tried lucas injector cleaner and heat water remover,and put 20.00 worth of premium fuel.engine has 2.500 miles on it.has new plugs and wires.and opti spark,but not 100% sure,because the guy said they are all new,the plugs and wires do seem to be.and also spayed some ether on the vacuum lines to check for air leak,any suggestion.thanks

wires not crossed,it was running great until other day,and also put scanner on it and showed no codes.it does have a exhaust leak on passenger side,must be loose.its night time heare and i just checked to see if plug wires are arching but no sign of it.

Opti vent harness? (vacuum lines). Have you checked to make sure they are both plugged into the opti ?

you could possible have burnt plug wires, car was doing same thing few weeks ago and changed the wires, and everythings back running right.

You have to stare under the hood in pitch black for a few minutes before your eyes adjust and allow you to see any arching if present.

I would look for any white spots or burn marks on your wires. How old is the coil?
