i returned my car from FI to N/A and i am having problems with the car after i revit up the rpm's drop to about 100to 200 but the car never dies. it slowly builds back. i had taken it to honda the other day and they said i was having vacume leak from my injector seals, i ordered new and installed them today. after the install i was having worse idling problems after i rev the engine. please help i have no idea what it could be. and yes i have double checked all lines

How did you re-connect all the ECU wiring back up? Maybe you got a couple mixed up? You put the OEM fuel pump back in?

MAP sensor wack?

the ems is a direct plug in to factory wire harness so it is 100% factory right now

I didn't realize that's you're using. I'm not all that well versed in the EMS, but has it been "tuned" to run a NA car?

lexar13

im not running the ems any more i pluged back in my stock ecu. and yes a ems can be tuned on a na car.

OK, just trying to determine the details of what you've done. Back to the issue of the fuel pump. The high output one still on? Just curious if maybe the stock FPR has faulted and you're running way too much fuel pressure.

lexar13

yes actually i do have it in i totally forgat about that. how can i check it to find out if thats my problem?

Check the fuel pressure at the rail to see if it meets specs. Any other details you may have forgotten to mention?

lexar13

no thats all i forgot :-). i checked the map sensor and did the steps you rcogmended in your other thread and if seems to be doing ok now but i dont know if thats a fluke or not so im about to go take it for a test drive.
