Dreaded AOS!

[bustingear]

Just spent the weekend f;)$@n with the aos and got it on. Payed special attention to get all the vacuum hook ups right but the "lil bastard 996 " 1999 will not run now. It wants to start and run but idles out. Before the replacent it was giving 1124 and 1126 which was lean. The module was adding gas to compensate. I disconnected battery during wrench session. No wonder it was running crappy the aos bellow was collapsed. What could be the issue? Anyone have suggestions?

Any fresh codes since you replaced the battery?

If it doesn't idle well, try cleaning the intake, throttle body, and idle air control valve.

Also make sure there are no major intake leaks and you put all of the hoses and boots back together properly, the car will not idle well (or even at all) when there are intake leaks, especially if they are big.

You may still need to get it on a smoke machine to find where the leaks are (as it's possible the AOS bellows was not the only cause).

Well thought about this all day off and on and it gave me new interest so I came home and went at it

I changed the MAF

Cleaned the IACV and sure enough when I pulled the TB I realized that I had not tightened both the inner clamps on the front intake boots! dam I did not think I was that bad:) after two days better to walk away for awhile and rethink it. It works.

YES! That was it.....running like King of Beasts looking for a meal........Thanks for the help too logray.

Good to hear, I've had my throttle body out many many times, and I must admit I've made the same mistake more than once. ;) Nice work.
