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

your problem is the mail order tune. I would suggest you find a shop to dyno tune it or someone that has hptuner. Mail order tunes are just good for bolt on cars and to get cars like your to the tuners.
