First to start with the low idle. I bought the car a year ago. It has MAFT, FMIC, 560 CC, Wbro 255 etc. I don't have a link and currently usingTMO and Evoscan. The problem is that when cold start it it idles very low( it did not for a year til last week) I think i have block off FIAV because i can see a copper plate which is sandwichted between FIAV and the other half of the TB. I changed the TB shaft seals. Something odd is till last week the car cold started like it has FIAV (the coolant lines are bypassed) idles at 1500 rpm then drop to normal 750-800 all year round. Other thing is i let her idle with my foot on the gas for a while and it idles close to 750 when i turn on the head lights it drops down almost dies sometimes dies. I checked alternator it is good 13.8( i had a doubt and changed it) i checked the ISC and the coils are good and also bought new one nothing change. Checked the ECU notthing obvious everything clean. Checked coils good, transistor pack good. I did BLT. I adjusted the BISS and nothing. CTS is good, timing good. So i am lost. The other problem is afer a drive and put her back in the garage the gauge on my AFPR reads about 15 psi. So my thought is i am having a bad pump,bad plugs(my wires are new) . Last sorry for my english :)
 
Thanks for the reply. I will check everything again but my main worry is when i switch head lights it wants to stall or it stalls. When i switch off it comes back to normal. I don't think that if i have a boost leak ( did have before and it was fixed) my car will start at idle so low like it does now. Pfffff DSM i love it. :). One thing i did not check is my plugs if they are opend or closed is it going to do this, also?
 
Your welcome, people on here have a hard time responding to badly written posts. If English isn't your first language, nobody will discriminate you for that, but you will find if you articulate your sentences better you will get more help.
If by open or closed you are referring to the gap of the spark plugs, then no. This more than likely would have nothing to do with it. If you haven't changed the spark plugs recently just change them just because. Use NGK bpr6es. But, by the characteristics you discribe above it defiantly has alternator/charging system symptoms to it. You say you replaced the alternator? Are you sure it's good. Double check all plug connector and power wires around the alternator. make sure no wires are grounding out or looked burnt or damaged.

I noticed that on the logger when i turn on the head lights my O2 reads 3.4v after i shut them off it shows 0.04. I spliced my wideband to pin 4( wite wire) for the gauge i took power 12v from the headlights. What is wrong?
