I have a b20b block and b 16 head in a 97 civic 2 dr coupe hx. I am using P72. The car starts at 1000 and when it is warmed up idles up to 1500. The question is, qhen i turn on my headlights my idle drops a little, also when i turn the heat up etc. This is only noticble when it is warming up. Is this a vacummn leak?
Also how can I tell what my transmission is? Where is the code or serial located?

Thanks
Khai
 
i remember on my crx i could adjust a cold start idle, and a warm idle. check that out possibly??

your cars should drop but recover when you turn accessories on. i dont think its a vacuum leak.
