mail order tune from texas speed

when i take it too 5500 rpms and have to slow down sometimes it will drop rpms to 400-500 and almost die but sometimes it wont and when it is running good it will be at 1000-1200 for idle is this right??? it is running extremly rich it burns the eyes its so rich!!! i have had the computer tuned. i still get a SES code of P0106 and have found no vacuum leaks can anyone shed some light on to what my idle problem could be??? i just cant figure this one out

 

surely someone has some kind of info???????

 

What kind of tune did you get after the install? Dyno tune, mail order tune, or someone local upload a tune for you?

 

He said he got a mail order tune from TSP. I would get a wide band on it and see how its running at WOT. Check the tune again. It also could be your Y pipe banging causing a false knock sensor warning.

 

thanks for the help i kind of new to the hole engine mods
what is a wide band??? im pretty sure the y pipe isnt hitting anything underneath the car.

 

It reads your air fuel ratio. It's also very common for H/C cars engine and exhaust to bang around in the engine bay with stock motor mounts causing a knock retard that will pull timing.

 

would this be able to be tuned out or do i have to change the motor mounts?????
