Bad Injectors????

[machineman]

My 11 pro developed a problem today. Weak idle wants to idle at 16-1700rpm and then fall off and die, thats not the big issue. The main problem is up to about 6400 rpm it has a a slight miss, then it goes away and runs like a dream. The "miss" does not feel like a electrical miss which is very pronounced. Changed plugs no change. You feel the miss in the seat of your pants like a slight "jerk" or "bump" Hard to explain in words. Any help appreciated.

Before you change injectors and reflash the ecu, try just running some good injector cleaner through the system.

I would also trim your plug wires and install new boots this seems to be a problem on them sleds

REEDS?

I had my reeds go out and it felt like it was running on one cylinder. Then would clean up and come on hard about 6300. My idle was way down before they really went bad. 3-4 pulls to start when warm. Would sometimes die when going to or from reverse. Might be worth checking. This was on a stock 13 with about 500 miles

check DC voltage at idle and TPS with multi-meter, not digital wrench. report back.
