P30 ECU - leaky capacitors replaced but car runs poorly
Hi!
I have a eg civic with b16a engine and p30 ECU. I got cel with VTEC spool solenoid valve but engine runs smooth just no vtec, I checked the solenoid directly with battery and it clicks meaning its ok. So I check the ECU and saw some leaking capacitors so I thought maybe its the capacitors so I changed all of them. After I changed the capacitors the car starts but has erratic idling on low rpm but sounds ok at higher rpm(didn't check beyond 3000rpm) and exhaust smells bad. I also got cel on.
Yesterday I checked the cel code and it gave me a map sensor code nothing else, but today it gave me a different code, today it was IACV which is code 14.
Any leads on what to check?
Thank you

Fixed my CEL prob already. Rechecked the ECU behind light and found out that some circuit were corroded by acid from bad capacitors. So I had to solder wire to connect them.
