misfire 1&2 new cop and plugs

[bholloway16]

Looking for help. I was at the light when my mm chk engine light came on, went to advance auto. It was reading 1&2 misfire. I bought 8 new cop (accel)and plugs and that didnt fix it. I done a compression test and they are fine. I took the cop off and they are firing. I don't kno what else to do. Dont have money for the dealer @ this point in time. Chking to see if anyone else had this problem.

Most people have stayed with the the Ford cops. Seems to be a problem with aftermarket ones. Are the plugs gapped to specs? How are the "springs" that connect from the coils to the plugs? Are the cop connections to the wiring harness good? Check the harness near the left ? drivers side of the cowl, is it rubbing on the bolt?

Have you looked at #1 & #2 plugs??:confused:

If you don't know they are the first two on the passenger's side as you face the car from the front.......I'd suspect bad plugs or broken 12 volt connector locks on the coils.....happened to me on one!!!:mad2:

Good Luck!!

Oh yes....Accels work fine too!!;)

Did you clear the codes and drive the car to see if it reappeared. You should always clear codes and see if they reappear before doing any repairs especially with mis-fires. Something as simple a mositure on the engine is cause a mis-fire.

When I changed my plugs recently, I noticed that the connector that plugs to the coil took some pressure til it clicked into place. Make sure all your coils are plugged in tight. Also make sure they are all the way down on the plug. I also used some di-eletric grease on the spring where it meets the plug.

Yeppers. Replace plugs, clear codes, use die electric grease. Make sure all is good and clean and tight.

I replace all the cops and reset the the computer. Now the light is off and the car is still skipping (misfiring) . The light flash when i'm drive now. I check to make sure they are firing by pulling the cops from the plugs. All of them are firing . I unplug a cop from the drive side and the car will change tune All my problem is on the right side.(passenger side. I went to a shop and they told me it electrical , but every thing is firing. I change the injector around and i'm still getting the same thing. i was thinking about changing the fuel pump.

How about changing ALL of the spark plugs??

If your light is flashing you definitely have a miss even if your enigne light is not on. Some COPS are not bad until they are under a load. I would get some good used COPS from the board members and replace all of them. But, you may just have a loose coil spring that is causing the problem. As was posted, you may want to check all the COPS springs before replacing the COPS and use the grease.

Ok my car was in shop for three weeks and they dont know what wrong.Its skipping and sputting. done a compession test all cylinder are 180 psi. Change the injector around and clean then. They repalced all cop's and plug's ,cam senor with ford motorcraft. They said it might be a head gasket but they aren't sure . Done a fuel pressure chk 40psi. I hate for them to do a head gasket and don't need when it going to cost me i'm trying to figure out how i'm going to pay them now. Do any one every went thur this.

I would think a bad head gasket would show up on a compression test...

Check the electrical connections under the master cylinder, maybe unplug and re-connect them (there are 3) to clean the contacts. Maybe unplug the connector from the PCM and re-connect it to clean the contacts. Be sure to disconnect the battery first. Also check the wiring harness where it goes from the connectors under the master cylinder and routes around the valve cover, sometimes the wiring harness rubs on the windshield wiper support bracket and it causes intermittent electrical gremlins. If it was the head gasket it should have showed up on the compression test.

edit: since they seem to be guessing and swapping parts until they hit on it, maybe they could try the crank position sensor.

There are nine possibilities for a mis-fire according to OBDII.com.

Seven of them you have seem to have eliminated. The last two are a faulty Catalytic Converter or a faulty Oxygen Sensor.

A faulty CAT can be tested on the car by an competent muffler shop. It's a warranty item for 8 years or 80 thousand miles.

Replacement of an O2 Sensor is not too expensive. Sometimes they don't go completely bad but react slowly or incorrectly.

Good Luck.

i just picked my car and its still not fix. They replaced the crk/cam senor,fuel pump/fliter which was reading 40 psi and they said it was dropping to 20 psi and would've fix my problem. (It didn't). They said it got be internal like a head gasket bc water is coming form the ex pipes. Water was coming from my ex when i both the car. I changed out the 1st 2 oxygen senor. Taking any helpful advice. The car dont have any power. You can easy on the gas until it picks up. If you press the gas its sputting and popping likes it not getting any gas. The engine light is not on. I stop by another shop and they told me it could be a valve bc you can hear my car running thur the intake and the intake is sucking a lot of air.i told him my compression is 180 psi all cylinders & leak down test was good.

Get rid of the Accel, go back to the stock cops

Wow this seems odd to me. No power could be clogged cats, the substrate could be broken up and choking your engine. You can remove them, get new gaskets from where the cats go to the H pipe, and new bolts.


The OBDII code is still saying 1-2 misfire? Tell me about the water coming from the pipes? It's normal to have condensation come from the exhaust pipes. After at idle for a few mins you will get water droplets coming out when you accelerate.

Try cleaning your MAF sensor with electrical contact cleaner.
