Re: Question about issues I am having
This has only happened twice to me, but may be worth a shot
I had two EEC-IV controlled stock rebuilds that ran HORRIBLE after I dropped them back in. In both cases, the first one after days of troubleshooting, the second one after minutes LOL
Do you have anyone that can do a hard erase of the codes? I never had a good reason why, but in both cases I went into my scanner and did what my Snap-on brick called a "hard erase" and they both started and idled like there was never anything wrong
In my experience, you can put quite a bit of cam in these before it gets crazy. Matter of fact if you had your cam specs we may be able to see if it really is too much. FWIW, you should be able to unhook the IAC and have it idle, if it doesn't you may need to open the TB a little and reset the TPS
However,try the reset first, I HATE that I never could explain why, but in both cases it was good running car drives in, I rebuild the motor and drop it back in, bad running motor LOL reset and drive away
