420A Did I read this CEL code right? I can't find my OBD connector.

1995 Eagle Talon ESI What Check Engine Light Code is this? - YouTube

Not sure how to embed my video with my phone here.

Are the CEL codes 12, 43, and 55?

Also, I can't find my OBD 2 connector. It's not underneath the steering column near my right knee like it should be? Where else could they have placed it?

EDIT: found the OBDII/OBD2 plug. That's not my leg either, I found this picture on the net that led me in the right direction.

I had to lay down and look up under the dash to see it. It's directly above the gas pedal.

yes that is your obd 2 connector

Thanks! I was right abt the CEL. Misfiring in all cylinders. I got a code pulled from my ECU from Autozone which said PO300 Random Multiple Misfires on their scanner.

Here is what I've done so far. I changed my battery bc an Oreilly Autoparts store that tested my battery said it was bad. I then changed out my spark plugs to new NGK Spark Plugs 2756 - BKR6E-11, new spark it wires (OMS 9458 Ignition Wire Set), and my ignition coil MPI 2-50013. The employee said I had to cut and hook up a pig tail connector to use the ign coil. An Autozone employee suggested that I try SeaFoam which I did.

My car bogs or has a hard time accelerating when I step in the gas pedal between 1000 - 2000 rpm. My top speed is 60 mph and it slowly has a hard time going higher than that.

What else I should look in to? Sensors? I'll be changing my air filter soon. Oil is good, and all fluids are too.

My car ran fine before I started to drive it around here a bit. It has been in a hot climate most if it's life till I had it shipped here where temperatures can reach 20. Could cold weather be affecting it? Some how?

you took mechanical advice from someone at a autozone/oriley? why did they sell you something that had to be cut, I replaced my whole ignition system and never had to cut the wires, because Mitsubishi put connectors on everything unless its because of the 420A. Seems very unlikely though... I would check and see if thats the right part like check the number on it physically. Stop driving until its fixed.

E: Was it running fine before? any mods or anything changed?

The ignition coil is a super-cession part number for the same engine in another chassis (dodge), that's why you need a pigtail for it. All of the big 3 US manufacturers do that pretty often in order to kill off redundant part numbers. Downfall is that the plastic wiring connectors are different. Us 4G63 owners don't really have to worry about that yet.

The parts you listed are all correct for a 420a DSM.

Your car most likely stumbles upon acceleration because of improper fueling. Things to investigate would be the front oxygen sensor, fuel filter and fuel pressure regulator. You should also make sure you gapped your new plugs to the right spec.

why did they sell you something that had to be cut, I replaced my whole ignition system and never had to cut the wires, because Mitsubishi put connectors on everything unless its because of the 420A. I wasn't too happy hacking off my connector either, but the employee at Oreilleys figured the manufacturer had change the connectors. It blew my mind too. Seems very unlikely though... I would check and see if thats the right part like check the number on it physically. Stop driving until its fixed. Its the right part, just for a later 95 I suppose. Of course I'm not driving it around, it's parked for sure till I get it running smoothly again

E: Was it running fine before? any mods or anything changed?

Yes it was running perfectly fine, upon driving 100 miles out from picking it up at the vehicle center and into semi-cold weather, I realized I couldn't accelerate past 60 mph. I pulled over and that's when the CEL came on and it started to sputter. Idle is steady at 850rpm. My car is bone stock. No mods at all.

Us 4G63 owners don't really have to worry about that yet. I see, it's the first time I didn't have a plug and play. My original ign coil is still new and I figured it was faulty so I changed it. Their wasn't any difference. The Oreillys down here said they'll be happy to give me a refund.

Thanks! I'll check those out. How do I check Fuel pressure?what should the gap be on the spark plugs? The Oreillys employee checked them and said they were good. The spark plug manufacturer doesn't mention the gap on the box. I do have a gap coin.


Thanks for the replies.
