ok finally got the 86 si started. its been pretty cold around here low 40s. and the only way we can get it to start up is if we prime it, or it its already been running and is warm. wen we start it and its cold the idle jumps from about 1200 to 900. once its warmed up it idles fine. my question is could this be because of the fuel injectors? also the gas that was in it was about 1 1/2 old, so were gunna drain the tank and put new gas in there. if it is the fuel injectors or even the old gas, what cleaners should i buy that will help clean the fuel lines and injectors. i know like stp makes sum stuff but is there anything u recommend? and any ideas on why it idles like it does? thank you
