Idling Issue

[P4rD0nM3]

Most of you know that I did a tune up on my 240 not so long ago.

I replaced the following parts:

O2 Sensor (OEM)
Spark Plugs (NGK Iridium Gapped at .042)
Spark Plug Wires (NGK)
New Distributor Cap
Oil Change
Oil Filter
Fixed Leaking Injectors

Since I have two other cars to drive me around town, the 240 hard parks for around 2 days before I miss start missing driving a 240.

So this is what happened.

Last week, Code 45 (Leaky Injector) appeared. I checked my injectors (Visually) for any leaks, I didn't find any...I don't smell gas or anything when I open the hood or a/c (It used to smell gas when I had a leaky injector).

So I took off the fuelrail and injectors and put i-1 to i-2...so I reset the ECU hoping it won't come back. But after around 10 miles...it was throwing me code 45 again. I ignored it for two more days and then the car started choking at around 3000 and then it idles like shit now.

It idles around 200. It used to idle at 750 or 800 and at 900 when ac is on.

Could it be the injector? I have no idea WHICH injector(s) is/are leaking and/or defective since I don't see any leaks at all when I look at it from the engine bay.

Could it be my spark plugs? I bought them from PDM Racing and they're Iridiums for the KA24E.

One thing that I noticed though is that it says...for HIGH REVVING KAs.

Mine's stock.

I did put the old spark plugs back and it idles good for a minute (Max is 5 mins.) then it idles like shit again.

Any other suggestions? Solutions?

Engine is a KA24E.
