One more thing I forgot to mention the trucks idle isn't smooth sometimes it will idle and sometimes it won't. If it is idling and I press on the accelerator it will sometimes cut off. I've had the truck tuned and it idled fine so something's went wrong?

I don't won't to throw money at it but from research it could be the igition switch. Has any of you replaced an igition switch and if so what lead you to replace it?


Thanks

 

Can you post your tune? I can take a look at it. Just did a 4l80 swap a month ago. I've done my own tuning and everything. I had the same codes thrown. Not the fuel related codes but the other 3 having to do with what trans. Even the 1810 codes. The are all related so the vehicle throws them all. I'll have to see some of your tables and settings to be able to help you but I had a segment swap gone wrong and that's why my truck threw those codes. I had to start from a base to from a truck just like mine and tune based on the mods.
