[quote name='rx7man629' date='Jul 19 2005, 10:31 AM']yea i kinda figured that, I ran the codes also and there was 17, which is feedback system and it said something about the o2 sesor so i replaced the o2 sensor for 17$, got out my tps tester light's and adjusted them and theres no more pulsing. Car runs a little smoother too, 17$ is nothing, i must of had the original on there.

i'm going to have to look up the FSM again, because for some reason i recall the O2 sensor having one other function besides running in closed loop cruise mode.

it could have SOMETHING to do with the surging, which could explain it on my car since it has never been working on my car (adjust cruise using SAFCII).



also, remember that you should adjust the TPS after a good hard drive so it's nice and hot up to operating temperature. i notice the resistance on mine changes quite a bit between cold and hot.

yea i made sure my engine was good and hot, Also today being the first day of the new 02 sensor in i drove to work and back and the car still shutters and the same code came up- i definatly can tell the o2 sensor helped the prob but the code is still coming up and the car shutters slightly. Im stumped https://www.nopistons.com/forums/pub...1047683561.gif

so you are getting a # 17 "feedback" system code?

[quote name='rx7man629' date='Jul 19 2005, 12:02 AM']well my temp gauge reads half way always when the car is warmed up-even when its below freezing out. it never moves from halfway, what can i do to get it to not be halfway?

drive at high rpms for awhile, that will heat that sucker up

i'm not at home right now, but check the FSM if there is any troubleshooting on that code.



i know i get that code quite often, doesn't seem to affect that much though...
