Checked valve clearances today - all like a charm!

The car starts only when gas pedal is pressed and has no idle...

Going to order new IAC and post the updates.

Get a leak down and compression test. The F2x engines are interference engines and there might be a bent valve or two from the time the motor ran miss aligned. You need to rule that out first before you chase the new miss fire issue. I am surprised it started at all if the cams were not installed right. Yours is the first report I have seen posted on a motor running with the cams misaligned.
Just finished - 14.8 bar in all 4 cylinders.
The engine's healthy i suppose...

Any further suggestions?

P.S. Going to test IAC again...
But those 7 degrees of knock at idle really bother me...
Just checked IAC and passed the 1st test - when disconnected the rpms rise to ~1000
but failed the second test when blocking 2 holes in throttle body - the engine dies...
Bad IAC or Hondata IMG has to do something with that??
Dilemma...

Hi, I'm having also problems with idle after installing iVtec cams and AEM V2 ECU (S2K AP1). Idle jumping 1000-1700 rpm and some times engines dies. Oven 2000 rpm engine is working quite OK.

I would like to follow the DTC troubleshooting, where can I find the complete document ? Step 4, 5 and 6 are missing in the images... Thanks.

4. Turn Ignition Switch to OFF

5. Remove the Intake air duct from the throttle Body

6. Start the engine and let it idle
