I have been having trouble with my teggy at idle. Here are the symptoms. When I start the car up in the morning it runs great. It idles around 1500 rpms while it warms up. My usual trip is about 5-10 mins and it runs good. I turn the car off and let it sit for any amount of time under about a half hour. Usually to go run arrands or something. I get back in, start the car up and the idle is around 500 rpms or lower. This also occurs if I drive the car for an extended period of time. At a stop sign or light I come to a stop and the idle dips to 500 or less. There is no surging idle and as far as I can tell no backfiring but my exhaust is pretty quiet so the most I can hear would be a slight popping at deceleration in gear. Also every once in a while the car will shut off at a stop but it starts right back up. There isnt a misfire code being thrown for it or anything else relating to idle. It just seems once the car is warmed up it cant hold the idle.

So here is my question. I know that many problems start at the IAVC but can this be caused by the TPS, wiring to the sensor or a BAD IAVC, Dizzy?

If it is the Dizzy would it throw a code and would I need to replace the whole thing?

I am replacing the AEM filter because its pretty bad could this cause the problem?

Finally I am throwing a P1106 barometric pressure sensor code. Could this cause the problem?

Please I need some help with this because I am running out of ideas and I just want the car to run right.

 

I have checked all of the vacuum lines and they seem to all be hooked up correctly. And I have cleaned the IAVC as well.

 

nothing? this site is useless

 

I know the agony u feel when nobody answers ur questions here..so I just wanted to drop my two cents. I had this problem..bought new o2 sensors and new dizzy and all..just to find out it was a bad iacv...so cleaning it might not help...since for example mine was completely screwed haha. Good luck with your teggy though!

 

What is your idle after warm up?

 

bump, having same problem

 

Clean the FICV and IACV with brake cleaner and see what happens.

 

Depending on what component that code goes to exactly I would go from there.
