Severe misfiring on 5.4L
Someone mentioned early on that it if nothing else pans out to check the cats. I will check O2 sensors and pressure at the cat (and probably start with full exhaust pressure test). What issues are there with the universal clamp in cats, if one is bad? Are the four different cats on the 2002...- gflat65

Severe misfiring on 5.4L
Changed out the alternator. The battery is charging now, but, against hope, it didn't affect the misfire. It accelerates, but seems to hit on power just every so often (like it's surging?). Worse as it gets warmer. I've got an exhaust leak on the right side that I've been using to hear the...- gflat65

Severe misfiring on 5.4L
Thanks guys. I'm going to test the alt today and see what that tells me. When it comes to COP's, is Motorcraft still the only real option, or has someone stepped up with another comparable option? I looked for Visteon's but couldn't find any at alanisdeals. I think changing the COP's would...- gflat65

Severe misfiring on 5.4L
Got the battery fully charged, and was able to connect to the ECU, but no codes were stored. It had a miss at idle (normally doesn't), so I pulled injector or cop plugs, and it seemed to change on #3, so I changed out the cop and went for a drive. It seemed to be doing well for a minute, then...- gflat65

Steering intermediate shaft
2002 expedition 5.4L The steering intermediate shaft is making noise. A new one is $300+. Can I knock off the UJoint section at the bottom and replace with an aftermarket UJoint section? They're $30... If not, I'll get the assembly. TIA- gflat65

Severe misfiring on 5.4L
2002 expedition 5.4L There is a severe misfire and hesitation at all speeds. I can't get my scanner to allow communications (scanner works on all of my other cars). I changed the fuel filter and did a sea foam treatment today. On the blow out drive, the battery light was on, went off, but...- gflat65
