ok its kinda hard to explain

I havent really noticed a steady pattern yet... at first i thought it was a 3500rpm hesitation problem but its doing it anywhere between 2800-3800ish. What it's doing is it starts jolting like crazy. If I were to step on the gas and quickly let off, step on the gas, quickly let off and repeat... thats what it's like. It's very jerky. It only jolts for about 100rpm... if i keep accelerating it stops after it climbs about 100rpm. It does it in every gear and at different rpms. I just had secondary injectors installed but thats not the problem because it was doing it before they were installed. So I looked at my car and noticed that the o2 sensor wire was cut. I figured that was the problem so i installed a new o2 sensor and did the wiring. Problem is still here. This hesitation happened just after I installed my s-afc... could it be because the s-afc isnt dyno tuned yet? I set all the basic settings so far that the manual tells u to do.

any help would be apreciated.

thanks

driving with the safc untuned can mess stuff up unless its set to not adjust anything (not doing anything). Could be also your TPS going whack at a certain spot (and hence different rpms in dif gears)...

Does it go away if you significantly change the throttle... say go WOT or no throttle?

 

If i go WOT u can barely feel it... its like a tenth of the second hesitation ....

 

sounds like your SAFC is not set up properly.

follow these instructions to set up the initial settings.

i followed those settings... thats wat i used to install it.. that exact site and the manual.

 

yeah, my car does the same thing and i havent been able to figure out what it is. someone said it could be the afm but i dont know about that.

 

was it installed in another car before yours? if it was then it may have a fuel map already loaded, check under the settings HI and LO setting and see if it is at 0 all the way across or if it has a previous map already loaded.

 

ok thanks ill do it tommorow... its brand new so it shouldnt have anything already loaded but who knows maybe my friend played around with it or something while i wasnt lookin :P

thanks
