hi guys... iam having a problem with my car. everything works fine when i did the swap with my 93 accord. but when your about to start the car the D4 light keeps flashing and keeps comming on. also when the car is started, the RPM and MPH keeps going on, even though its on park. is it because the D4 lights keep flashing or something, let me know if you guys can help. also sometimes my car would start, and sometimes it would not, it would just crank only... let me know if you guys know whats wrong with it, and let me know if you guys can help, thanks... or you can send some infor to sniper1837@yahoo.com

Possibly a loose electrical connection?

do you know which electrical connections and for what?

Sorry, I've never swaped an engine, and have little idea on what kind of sensors, and whatnot you have to deal with.

I had a problem with the D4 light flashing. It was a broken... and I mean broken, temperature sending unit. It's the larger of two sensors in the head under the distributer. I replaced it... $26.00 at Advance, and it stopped blinking. I can't help you with the other problem.
