My idle was running rough and slight loss of power (5 cylinder engine). The power loss is more noticeable on cars with less cylinders.
The car may misfire or not accelerate properly
Need to know the year, so we can answer correctly.
The vehicle will have low compression causing it to misfire and not run
I hope your barb was a misfire.
You can find almost anything you need to know about the V Star 1300's engine misfire here; http://forums.delphiforums.com/vstar1300t/messages?msg=149.1
Need to know what year and what engine to help you.
It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.
Random misfire, cylinder 2 misfire, and cylinder 3 misfire. see related question below.
How do u fix a misfire
Misfire in Cylinder No. 8.
Were the spark plug wires replaced? Even a pinhole in a plug wire can leak enough spark to cause a misfire. Try swapping that wire with another similar length wire from another plug and see where the misfire is then. If the misfire moves to the new cylinder or ceases completely, you'll know the wire was bad.
A loaded gun fails to fire when the trigger is pulled- misfire.
