Gremlin help
Hi all,
Need some troubleshooting help pleeeeaaaseeee. Wits end. 2002 EFI twin cam Softail Heritage Classic. I think it's starting to run on 1 cylinder - the back one is dropping off. Not enough to throw a code yet but it's happening. Background - this happened last autumn before the winter and an indy I bring it to troubleshot it and eventually said it was the coil. He replaced that, the plugs, and the wires. Ran good but it was then the winter - only had it out a few times for commuting in decent weather (about 20 miles one way). Now it just started again when I took her out of the garage on a ride around town. Smelled like gas when I parked back in the garage. No power past around 40 mphs, a little popping on decel, sometimes jerking/surging like a rodeo when I try and roll the throttle on.
If the coil and spark is good, fuel injector for that cylinder? Air cleaner is clean. Clutch and plates are fine and have been inspected. New Power Commander 6 and crank position sensor last year. What would be the next easiest thing to troubleshoot?

There are a number things that can cause this.
Kinda thinking start from the beginning
Ck connections at coil
Ck the plugs and if you have an extra set replace them.
