I am trying to figure out what the hell is going wrong. I did a zc swap not too long ago, basically a stock 91 si replacement. Well now I am having problems with it idling, I changed the EACV, TPS, coil, got new plugs, brand new nology hotwires, fuel filter, and checked for vaccum leaks, all that did no good, I checked all my wiring to see if it was getting voltage to the sensors, they were. MAP sensor resistance was fine, Only thing is I am missing a ambient atmospheric pressure sensor or some shit like that but it ran fine without it before. Well it started out as the idle just going back and forth from 1500 rpms and dropping to 1000, pretty damn embarrasing at stop lights...Well anyways now it is very hard to get it to start, some guy tells me it flooding out thats why it dies but the only way to keep it running is to keep the rpms at at least 2000, oh and I changed the pressure regulator too so its not that. Well tell me what yall think, hopefully someone can tell me what the deal is before I have to take it to the shop. Oh yeah and I have a chipped PR4 integra ls ecu on it, actually gave me a good hp kick, you cant even keep it running with the stock ecu now, figured that may be helpful. thanks in advance whoever can help me
