Ok i Have A 1993 Accord With An F22b1 Swap . I Know They are a couple threads on here which deals with Vtec issues and yes i have searched and tried what i have read, but nothing has worked so far. At one time Vtec did engage and car ran perfect even with a CEL light on witch was 02 sensor but here is where my troubles began. I helped out a friend with his F22b1 swap, just to verify the engine was running correctly, I swapped in my ECU To His Vehicle, once i put back the ECU on my car it started to bog at 5000 rpm and ran like garbage so i jumped the ECU plug to read the codes and got 02 sensor and Vtec pressure switch. ok cool, switched out the pressure switch but nothing, switched the whole Vtec but nothing. Checked for current had no current, so i ran new wires to the Vtec but still nothing. Changed the ECU 3 times, and nothing. I have ran out of ideas and patience so can some one please give me some input on what i haven't tried or what i can try it will be greatly appreciated. thanks!
