jefflambo Report post Posted February 11, 2011 No the exhaust wont change or effect the map reading. I would delete the code and see if it returns. Quote Share this post Link to post Share on other sites More sharing options...
djantlive Report post Posted February 11, 2011 any symptom? how is the engine running? idle ok? may just be a sensor issue. i'd agree that you can erase and see if it comes back. i'd also check if anything around the manifold is loose - vaccuum line etc. also, see if switching to different brand of gas helps.

The MAP referring to the Fuel/ air ratio mapping? If you changed the exhaust and filter, you altering the ratio right? Quote Share this post Link to post Share on other sites More sharing options...

The engine running ok accept some nervous at idle, bouncing a little, stall once. I will try clear it and sees what happen. Tks for help...

Yes it will change some but the o2 sensor can more then adj. for the change in exhaust & filter. It will run a new self learn when oil temp and coolant temps are above 90c. and the purg it off. There is nothing you need to do the car will do it on its own when the conditions are right. Once it runs a new self learn ideal should be normal. Glad you like it.

I tried clear it , but my OBD scanner saids, error clearing the code, turn key on and engine off and try again....etc The light did went away once, only once, but on ever since... Tried cheaper gas , still no help. Quote Share this post Link to post Share on other sites More sharing options...
henry47 Report post Posted August 25, 2017 any luck with this particular code of p1106? Do you know if it ended up being the o2 sensors or if it was something else like the map sensor? Quote Share this post Link to post Share on other sites More sharing options...
