So starting today, my pony has been doing some really weird things (or thing). So normally it idles around 750rpm. Which I believe is normal. Well this morning all of a sudden it is idling (when warm, not exactly sure about cold) between 450-550rpm. So that is weird enough, but not really a show stopper. However, the issue is, that it has a couple of times died when trying to start out from a stop. After 2.5 years I have subconsciously learned the amount I need to kick it up when letting the clutch out. Well now that doesn't seem to be enough. It is bascially like I let the clutch out while in gear (but it is softer then just dumping the clutch normally would be). Any thoughts on what the heck might be going on here? I'm not exactly sure where to start looking for this funness...I could use some help to at the very least get me started.

Thanks in advance.

 

Sounds like it's time for a new fuel filter.

 

I'm assuming there are no codes yet. I would start with the throttle body they get dirty easily. There is a TSB on them to. You might want to reload your tune. Some people have hadsimilar issueswhere they just reloaded the tune and the problem went away. I am no mechanic.

 

Fuel filter is less than 5K old...so I doubt that may be it. What is the TSB on the TB? What is the problem with it?

I can take the intake off tonight and see how dirty the TB and maybe see about reloading the tune.

Any other ideas?

 

My TB cracked...replaced for free...donno if it was because of the TSB or not.

 

I have some carb cleaner at home is it similar enough to TB cleaner, or do I need to get me a can of TB cleaner?

 

Carb cleaner is not the same, the throttle body has some kind of teflon coating on it & carb cleaner will remove the coating, buy some TB cleaner.

 

+1 on cleaning the throttle body. I had the same symtoms, cleaned the TB, with TB cleaner, NOT carb cleaner, and problem solved...This is what mine looked like with only about 15K on the dial......

Everyone is pointing you in the right direction to start with.

 

Took some TB cleaner to it tonight when I got home was cleaner than the above, but still fairly dirty.

I also reflashed my tune.

So between those two I have covered all of the bases posted so far...checked TB for cracks it was crack free.

So we'll see how she does tomorrow.

I'll let everyone know.
