UPDATE Checked the spark plugs today and they're black, so it is definitely running rich. A little more research has told me that other people with similar problems have just switched from the JDM P13 to the USDM P13 and it solved their issues. Apparently the H22A head flows more air than the...

Hey HondaSwap, I recently put an OBD2b USDM H22A4 in my '00 EK, running on a stock OBD1 JDM P13 ecu. I used to have a boosted D in my car and can usually trouble shoot issues concerning Air/Fuel ratios, but searching has shown me there seems to be a lot of people that have no idea what...

I put the 345cc injectors in it and it woke up significantly. Thanks for the help!

What happens if you unplug your IACV?

Hey HondaSwap! So for anyone that read my last thread, you know that I've put an OBD2b H22A4 in my '00 EK. I've run into a small dilemma and I'm looking for a little advice. When I did my swap, I decided to go OBD1 because the Prelude I took my engine from was a 2001 and had a Key Immobilizer...

Hey folks, Looking for a set of 345cc H22A injectors. Let me know what you've got and how much you want for them. Also will need to be shipped to Canada, but I can pay shipping. Thanks!

A little eye candy of my swap.

Alright so I took off the IAC and throttle body, and thoroughly cleaned both with some Throttle body cleaner. When i put them back on, the idle surge seemed to have dropped quite a bit so I'm guessing the IAC had been part of the problem. I went over each of the intake manifold nuts and made...

Thanks for the fast reply! I haven't checked the TPS yet, I'm going to do that tomorrow. I don't really have a spare one around that I know of, but I'm going to see if I can't borrow an H22 throttle body from a buddy. I've checked all the vacuum lines and I don't see anything unplugged. I'm...

Update I changed the Intake manifold gasket today. The car is still surging, but it's acting a little differently. The surge seems to raise slower than before. I can also cover the throttle body with my hand and the car idles down, but still surges. I've also found that if I unplug the TPS...

Thanks for the heads up. I ordered the IM gasket kit today, so it should be here by the end of the week.

The FITV is attached to the throttle body on the bottom, just like a D series. I cleaned the IACV and I've confirmed that it's working. The car idle surges right from start up. After spending a few hours diagnosing I think i've narrowed it down to being a vacuum leak. I can hold my hand over...

I appreciate the feedback fellas. CAFROG - I wasn't aware that the FITV controlled idle for OBD1 motors. I checked it and although it was a little loose, it didn't make a difference - the car still surges like a whore. Chaz - I'm running a conversion harness from my harness to my ECU. You can...

Thanks for the fast reply! I didn't mention that the engine ran perfect in the Prelude before I pulled it out, so I have a good feeling that the FITV isn't the culprit. Someone suggested I run a Civic IACV on the H22. Has anyone else done this?

Whats up Honda Swap!? I've been lurking here for a long time as a guest and finally decided to post and ask about a swap I just did. I've searched and searched to no avail, so hopefully I get some answers here. I recently put a OBD2b H22A4 in my 2000 Civic sedan (came stock with an OBD2b...
