Hmmm..afv..¿?

[chaselantern]

So today I took it to work. Was okay tell about 10 kms in (20 or so min of riding) . It started to pop and backfire out of the intake. Slowly progressively got worse .Huge power loss, almost stalling. I figured afv out of wack so I pulled over reset the tps and took it to the highway. I noticed it ran better at highway speeds within 2 min.. when I got back in to the city it ran awesome. Crazy good power and no backfiring or intake bombs.. highway to my place is a 5 min ride. any ideas??

Can you run diagnostics with ecmspy or buelltooth? Check your tps sensor.

I'm using bluetooth and no codes.tps said 4.2°
Its really cold outside. Not sure if that makes a difference. 7°C

Just the one anomaly?
Check your AFV on ECMDroid and see where it is.
TPS re-set is a completely different thing.

Yes so far.just the one. Afv is 91% in the back and 94% in front.

Just got to work and checked the afv. 94% for back and 86% for front (City driving). it was 0°c for temperature freaking cold.. When I drive hightway speeds the afv go back to mid 90s. Not sure if this helps?

I just got goosebumps thinking about your ride to work! It's a chilly 63*F for my block and a half walk to work thins morning, I might need a tuque!!
Thats certainly low, but if its running ok I'd leave it alone.

If the coughing happens again, check that first. Obviously low IAT has some influence.

Maybe a low battery caused by high current drain and low RPM's? I'm sure you've got all the heated gear you can wear cranked to max!

Just spitballing for now...

I had a similar stumbling/ popping after riding halfway to work that ended up being a barely loose battery cable. I'm far from an expert, but something to check.

Okay! So the problem hasent happened again. Hopefully won't ever happen again. I have put about 200 km on since first post and no probkems. One thing I have noticed after frequently checking afv is every time I drive on the highway I gain more power because my % Is 95ish. I can actually fell a difference. Lol (way easier to wheelie). When drive in the city my % drops to 85ish.. ugg any ideas?..
