cant get a good idle

[280tyler]

i finally got my car started and the problems worked out with the usb adepter but I'm still having problems getting it to run right when i start it up it is missing prity bad and my wide band is showing rich spikes but if i rev it up the engine will excell good no misses no rich spikes until it comes back down then it will start to miss again. i tried holding it at a higher rpm but it would still pop and miss. all so i cant get the car even to run with my laptop unhooked it will just die

 

it is confusing me because it's not a Constance miss

 

I'm kinda stuck any thing will help thanks

1) Dont use the 02 sensor yet. Wait until it runs OK and then later fine tune with the WB O2.

1b) Confirm all the sensors are properly talking to MS one-by-one. Use the Stim board to make sure MS is working right.

2) Make sure MS Timing shows the same as a timing light on #1 cylinder.

3) Make sure you have no vacuum leaks and check your idle stop screw and your idle air control, if you are using one.

4) Raise/Lower your ReqFuel or VE cell with the engine idling until it smooths out.

 

Good luck
