Hey all. I have a 93 civic sedan with a B18B1. It started throwing codes last night. When I checked them i pulled code 3 MAP, 7 TPS, and 9 CYP. I checked in the bay and disconnected the MAP and TSP and to see if it affected the running. After I disconnected them and reconnected them I disconnected the battery and rechecked for the codes and now i am only Throwing 9. It runs fine once it gets started. It has a real hard time starting if i don't press the throttle in. I don't really know where i should start. Any suggestions and help would be great.

Thanks guys. So this morning i had a rough time starting her up but she got going and was running fine. Car sat most the day at work. Went to get ready to leave and started her up with no problem. CEL is gone. Checked for codes, NOTHING! Its like the whole problem just vanished. I am going to keep my eye on this and start putting some moneys aside for a dizzy just incase this comes back. This car is the darndest. Has a mind of her own.

 

Could be a wiring issue also. I always suspect wiring first on swapped cars, mostly because of some of the wiring nightmares I've seen.. So keep that in mind, it could be a poor connection or something like that. Could be a sensor power or sensor ground problem because it's affecting more than one sensor.

Keep an eye on it and see if comes back, other than that it's just about impossible to troubleshoot when it's working properly.

 

thanks. yeah, some of the wiring is crazy to say the least. i have gone thru some of it and traced back wires to just dead ends. and other wires that just were there for now reason at all. so its been a slow clean up. Thanks for the help guys. i really appreciate it
