Help...96 Outback 2.5 Cylinder 4 Misfire

cedata · 05-09-2004, 09:29 PM

My Outback is a 96 2.5 w/150k miles. Some months ago I got a check engine light. Code idicates cylinder 4 misfire. I have swapped the plug, ignition wire and fuel injector with other cylinders to see if problem follows part. I finally bought a new ignitor pack. No help. I would greatly appeciate any suggestion that might help me resolve this. Thanks..Cedata

So the CEL is still on right?

How is the car running, is it using lots of gas, shaky, hesitation?

do you have any mods?

i has a missfire is cylinder 2, the car studdered one time and a stop light and the cel came on and wouldn't go off, until i had the dealership clear it. never came back (only been 3k miles).

How are you pulling the codes?, yourself or a shop/friend?

Are you getting the same CEL?

Common issue is bad plug (or new ones that are bad for our car, like Bosch plugs)/bad wire.

When was the last tuneup? Even though you may have swapped parts, doing new NGK copper plugs and OEM wires is a good start.

Can you add anything to this?

Thanks for the response...My car is not modified in any way.I bought an OBDII diagnostic package from Ease Diagnostics a couple of years ago. Works great for reading and clearing codes. I'll take your advice and buy NGK plugs and factory wires. If that will work it will be an easy fix. I replaced plugs (used bosch)and wires (got'em at AutoZone) last year. When I initially start the car it idles great...I drive down the road a minute or two and suddenly I can tell it runs a little rough and CEL flashes.Car will run rough for a minute or two then everything smooths out and the car runs great . Thanks, for your help. If you have any other thoughts on this let me know...Dave (CEData)

bosch are bad. they just dont fit up well with the factory plug wire boot on most cars. and if they are split fire they are worse yet. all those electrode prongs do is block fuel from getting to the spark.
