et running like a rotary, not pulling and hard starting
et running like a rotary, not pulling and hard starting
so the last few days the pulsar has been spluttering when u put ya foot down, but only for 1-2 seconds then clears up, but at full boost u can hear it struggling hard. have checked all hoses, leads etc. im thinking AFM? atm it wont even start, but it gets goin eventually. weird part is, it comes good some times and pulls normally. almost like it goes into shock mode then back out, but sometimes stays on forever.
Ecu is best bet.
Other things to check, clogged Air Filter, sticky MAF flap, incorrectly adjusted AFM Spring (doubtful unless you've fiddled), dirty/loose AFM wiring plug, clogged Fuel Filter, dirty Injectors, Injector leads/plugs (Clean the terminals anyway, wont hurt, and they can get fairly dirty), and it may sound weird but TPS (I know mine was a pig when the TPS was adjusted wrong).
Being intermittent sound like something loose in the wiring to me, but I've seen partially clogged "bits" cause a similar issue, a bit of a rattle causes them to free enough to flow, but then another rattle causes them to clog up again.

afm
ok, so i adjusted the screw in the afm. did it all the way up, then 2 4 6 8 10 turns and all the way out and it didnt change the mixtures. so i think its fair 2 say the afm is royally fucked. blows black smoke, pops, have to start with full throttle so it doesnt foul up.
My favorite minor issue is the water temp sensor.
Try this out, start the engine and get it to operating temp. When its upto temp, unplug the sensor. The engine should literally die within seconds from being massively rich. If you have messed with the afm settings and got it to run without the sensor, unplugging it wont have any effect.
If this is the case, I'd be cleaning its terminals and the harness connections. Mind you, if the senor is now working as intended, the engine will run rough from messing with the AFM.

Ummmmmm....... Factory or non factory ecu won't operate correctly with only some of its sensors!

No just a whole heap of more advanced problems, choose wisely and learn all you can before going down that path. I didn't learn, went down that path and now my computer guru is leaving me for warmer climates. I choose lt10 because of a good deal but have had an amount of issues so choose carefully.sashN12 wrote:Lol need an aftermarket computer, wouldn't have these problems lol

Coolant Temp Sensor m8.
Damo has already mentioned it.
If there is a wiring issue or the sensor is dead the thing will default to rich as buggery.
Try another one. Just plug it in hanging in the breeze. It wont matter for the purposes of the exercise and the sensor itself does not need to be earthed.
Mixture screw on the AFM is simply and air bypass and either slightly opens or closes the flapper door in the afm to trim fuel and will have NO effect at any throttle except idle.
