Hi dudes,

I have one problem after the H22A4 was installed on my 92 Prelude (automatic). When I rev the engine up around 4800 rpm (vtec kicks in) with tranmission engaged, the red engine light will come on (code 1). If the tramission is not engaged, the problem would never come on (the engine light does not come on ,even up to red line). I already replaced a new NTK(NGK O2 sensor , part#: 24172, but the problem still not being solved. Therefore, I doubt the issue comes from transmission's controller (computer) becasue I did not replace it in JDM one, is it?

Here is what I have done on my car.

I installed:

- North American's H22A4 motor (2000 prelude)
- JDM OBD1 SR-V automatic ECU
- OBD1 fuel injectors

PLEASE help me to resolve this issue becasue it is so annoying after I installed the H22A4 motor. It suppose to be faster with Vtec, right ... so now its no FUN at all ! Please give me a hand , GUYS !

**PS: You may send me private message if you prefer, Thanks !


Thank you so so much !
