im posting this for a friend

A friend of mine owns a 91 ef hatch with a jdm dohc ZC swap. He originally had a problem with his TPS sensor, so he swapped it for another zc tb and the car ran good during the day. NOW, the problem is that the car runs extremely rich. he's using an 89 integra computer, p07 i believe. besides the fact that the car runs extremely rich, it also bogs in every single gear but reverse. It's as if it doesnt wanna go. the tach is jumping up and down when you drive. the charge light doesnt come on, but could the charging system have something to do with that? its throwing a few codes, ill have to ask him what codes they are. but does anybody have any idea what could be wrong. earlier in the day the car ran fairly decent, the idle was fluctuating a bit, but it drove fine. would the drop in temperature have anything to do with the car bogging? there is also one, im assuming, pcv valve on the tb not connected, appartently there was an extra one but no hose to connect to it. possible cause of the problem? should this be plugged? any help would be appreciated. thanx

 

PG7 will make it run a bit rich...you probably have a bad distributor as well...change that with a known good one and see what happens...
