Hey guys,
THIS IS LONG, BUT I WANT TO FULLY EXPLAIN THE PROBLEM.
We have a 2005 ford expy and are the original owners. For about a year, my wife and I noticed a stumble when sitting at traffic lights that progressively got worse. i didn't sweat it as it wasn't throwing a code. PLugs replaced about years ago, mileage 105k or so.
In October 2012, it threw code 307. At that time, I researched the issue and people mostly pointed to coils. I bought a set of 10 off of ebay form a supplier people were reporting good results and replaced it. Vehicle seemed to run better, so I replaced all but cylinders 4 and 5 (haven't been able to easily reach them as they are under the ecu).
We stopped dring the vehicle daily and very occasionally drive it now. I got a mountain bike and started using the expy to go on rides and it progressively started running much worse. While driving it gently about a week ago, we heard a long "knock event," about 5-6 quick cylinder pings, then the check engine light came on. Checked it with my code reader and got:
p0307 - CYLINDER #7 - MISFIRE DETECTED
p0307 (twice)
p0357 - IGNITION COIL "G" (COP-G) PRIMARY CONTROL CIRCUIT / OPEN
Hmmm... maybe the COP was bad? cleared codes and replaced it with a spare new one, no change in running.
Drove it one more time when we needed to haul a car load of kids. Bad idea. started bucking pretty badly, CEL came on, CEL started flashing! Just echedked codes today and here is what I now have:
p0304 - cylinder 4 misfire
po307 - cylinder 7 misfire
p0300 - random/multiple misfires detected
OK, so now cylinder 7 is misfiring again and cylinder 4. I don't think it is a bunch of bad COPs as I changed cylinder 7 once and then have not changed cylinder 4. I also don't think it is something affecting all of one bank, sunce 4 and 7 are in different banks.
My leading suspicion is injector problems since the issues on the 2005s and extended warranty, but I can't be 100% sure. Customer Satisfaction Program 07M08 is the letter extendign the warranty.
QUESTIONS:
- Any suspicion of the problem?
- How do I take it tot the dealer and have them focus on the injector warranty work without charging me for a bunch of other BS items? I just don't trust the dealers and I can picture then wanting to change all the plugs, change all the cops back to oem, etc. only to find out its not that.
Thanks for any and all help in advance! I really don't want to dump a lot of money into this thing as its only a 3rd vehicle for us now.
