I've had the same idle issues with my car as well. I've gotten misfire codes, crank sensor codes, and O2 heater codes. I've replaced just about every sensor on the car, including switching to Bosch 11131 sensors with opened up caps and cut down O2 bungs. It seems to me that this might be related to the O2's correcting for false lean like others have mentioned because when my car was tuned, it ran and idled great till after we turned the O2's back on. Then it started surging and dying again. I think I remember a comment about it looking like I had a vacuum leak while we were tuning. I suppose this might be because my cam is on a 110 split with a 228/230? Anyway, I think we might do away with the O2's next time we go out and see what happens.

Thanks Tony!
A mail-order tune is actually a good way to get your car tuned for guys who don't have dynos/tuners in their backyard. We can get you VERY close for the tune of just about any cam or heads/cam setup. That being said, they aren't all perfect. That is why we offer free retunes. Also, on idle issues, a lot can be done with the TB set-screw. Sometimes, it does take more than simply plugging the PCM into the car to make it idle the way the computer is wanting. Opening and closing the set-screw is a good way to adjust the way the car idles and recovers to the set idle RPM. We always encourage customers to check the tune on a dyno and send the PCM back to us for any minor tweaks and adjustments that might be needed. If you use them properly and take advantage of the offers, mail order tunes are a great and effective way to get your car tuned properly!

This is much better than running big cams on stock tunes.

If it was running good after the tune and then started going bad why do you think its the tune? Its a freeking ECU. The timing can't walk and there is no way the tune went bad. Its something to do with the car or environment. Cars with ECU's dont just go out of tune. Something happens to change the variables wich effects how the car now runs. Its not becasue a vendor didnt tune it good or a certain vendors tune loses its perameters. Thats **** doesnt happen. Its a big friggin cam. Maybe the real issue is a vacuum leak, or a sensor going bad. OR a stock bottom end being spun to hi and have created an other issue. Maybe its a burnt plug wire.
Mail order tunes are not a first choice but they arent a bad alternative to doing nothing.
