Hard starting

[burgerbone]

I just put my Nytro back together, runs great, only problem is that I need to give it a bit of throttle to get it started.

Hot cold same issue.

At first it wouldn't hold idle but that's fine now, its just hard starting.

All the hoses to the throttle body are connected, maybe a bad throttle cable?

Did you mess up the idle?

 

[burgerbone]

idle sits fine around 1400 - 1500 RPM, I thought this was computer controlled.

They will have a adjustment to open the throttle bodies ...

 

[burgerbone]

I have no idea how to adjust the idle.

If you crack the throttle ever so slightly will it fire?

 

[burgerbone]

Yes, then it idles fine.

 

[MrSled]

Yes, then it idles fine.

and then if you let off it will die and or the sled is hard to fire? Follow the throttle cable down to the rack and look for the linkage and adjuster screw on the rack that all the TBs are tide too. On the Apex there is a little box and linkage with a small thumb screw... I cant remember exactly wear the adjustment is on the Nytro. It also need new plugs if you are sure that you didnt bump that idle adjust.... maybe the plugs are slightly fouled.

I previously had K&N filters on but put the stock airbox back on. Do you think this could be part of the problem?

Do you have a few controller?

 

[burgerbone]

I removed it. I did the diagnostics and everything seems to test out.

I guess I'll try adjusting that screw on the throttle body and see what happens.

Change the plugs....had the same issue recently

 

[burgerbone]

Plugs look ok. I turned that idle screw out about 2 or 3 turns, seems better but I'm not convinced that was the problem. Why would that screw even be turned in that much in the first place

Does it run normal?

 

[burgerbone]

Yes it does thanks. Just doesn't explain why I had to do 3 or 4 turns out to get it to start properly when I never touched it. I was originally thinking throttle cable.
