Sanned my computer

[lincoln_zero]

Scanned my 2005 that i posted about earlier this week. The "hesitation when accelerating" problem.
Using the OBDII scanner, here is the error code i got:

 

[G-RELL]

cool

-_-

Anyone know what that error code is for? I understand its cylinder 1, but whats this system efficiency error? Bad plag or bad coil?

I thought that meant your cat is bad, or atleast something to do with the O2 reading something off in your cats, like too much fuel and such.

Not cylinder one, bank one (cylinders 1 to 4 or cylinders 1 to 3). This is the right side.

This cat damage is not why you are having "hesitation when accelerating." It's a result of the same problem that is causing the hesitation. You have one or more (probably more) COPs (Coil-On-Plug) that are marginal, and have been for some time now.

The correct solution is to replace all COPS and all spark plugs. After that, you may find that you still need to replace the right catalytic converter.

Since you have an 05, if you have less than 100K miles and it is a V8, you can take it to a Ford or Lincoln dealer and they will stress test the coils and replace any that fail at no charge under an extended warranty customer satisfaction program.

Ok so now you say "100,000 MILES"
Im in Canada. Its got 136,000 Kilometers (roughly 81, 600 miles)
So i should be in the clear. Ill contact ford about it.

@G-Rell that link to Google made me Laugh out loud hahahaha

good info there

Also, Joegr,

when i call ford about it, how do i present my case? cuz ive only got 81,000 miles. Do i say "Hey, i found a recall on this issue"?

thanks everyone for your replies

The Canadians got a different letter and a different warranty extension. I'm not sure which years it covers and for how far. As you said, you'll have to check with them. I'd look for the biggest Lincoln dealer nearby, because not all of them know about this program. Over here, it's "Customer Satisfaction Program 07M07." It's not a recall.

Thank you soooo much!!!!!!! Called ford and they acknowledged the program.
My appointment is for tomorrow at 2Pm.

At first they didn't find the program, howver once i said "Customer Satisfaction Program 07M07" they suddenly remembered it. :shifty:

Anyways service Rep told me that if the problem is related to 07M07 then its free. Otherwise if its a totally unrelated problem, like if its the 02 sensors, then i pay the diagnostic fee of $100.

Something else caught me eye. On this forum, i found an older thread, where someone with this issue had pulled his battery for 30 minutes (he did his sparks and has issues. So he pulled his battery) which reset the cimputer and the problem went away.

You think this could be related to that as well?

No, I don't.

While you are there, you might check into what the Canadian law is on emissions components, like the catalytic converters. You might luck out and get that covered too.

 

[lincoln_zero]

Ok ill check into that! Would make sense they replace the cat if this problem damaged it.

 

[lincoln_zero]

Just out of plain curiosity, i pulled the battery for an hour. Plugged it back in.. and took it for a spin.. the problem did not return.. Drove it for an hour.

Anyways i let the car cool off and now im gonna go for a spin again. Keep you updated.

I get this code (actually 2 codes for both banks) because of not having cats currently, if i clear the CELs, it usually takes three or four days for the system to complete its cycle and for them to pop back up. yours may even take longer depending on how bad your cat are. I wouldn't have cleared the computer until after the dealer took a look at it though, but thats just me.

 

[jrand]

joegrs right, 80k with original coils is probably your issue. code might disappear after coil change. lucky you, lincoln has it covered. if one dealership dicks you around just call another ford dealer. some dealers were shifty with work that would be free when i called. and you are right, if you ask them if they have a recall or extended warranty program to cover something and dont have the document stating that they promised to cover it, they will play dumb and all kinds of sh*t. some even still refused to do the work. i knew what i had the right to get replaced for free and would only go to the dealer who told me exactly what i was entitled to get without my specific mention of my right. my 2 cents if they are trying to pull one over on you right off the bat you know theyre going to try it again at some pt

 

[lincoln_zero]

I went to the dealer today. The service center guy seemed honest. He told me the error code was a catalytic converter code and to replace the cats. Now, he told me he didn't want to start charging me for diagnostics and that if i could do the cats myself i should. He said those shakes are back pressure.

Which makes sense that its back pressure. Because it only happens when i push the car at 3000 rpm, and its dumping exhaust. He says that the previous owner must have driven wit the engine light on, and polluted the bank 1 cat.

At any rate, he was confident that error code is Cat. What do you guys think?

I had the same code a couple weeks ago.... After messing with the reader for a while he told me I also had a mass air flow sensor code. I cleaned the sensor and the engine light went off after some driving. Took care of both codes

 

[joegr]

Yes, absolutely that error code indicates a problem with the catalytic converter on the right side.

What it doesn't say is why. The usual answer to that is misfires due to marginal coils. Marginal coils almost never trigger a code, so you won't have any code showing for that.

Yes, it's possible that the cat is so bad that you have too much back pressure and that is why you engine isn't running right. However, it's not often that they get that bad. You can temporarily remove the front right side O2 sensor and see if it runs correctly with it out. If that resolves your problem, then the cat really is clogged. If it doesn't, then we're back to a misfire problem.

Thats great for diagnosing the root of the problem, however the service center guy says that the check engine light is not on (which its not) and i have no proof its the coils. Ford only extends the warrante if its the coils. Their scanner may not turn up as coils and i just waste $100 for a scan.

Ill do as you said by unplugging the sensor but i dont know if i can make good with this extended warrante thing.. Dealers seem to not wanna do free work LOL even tho they bill Ford for the work.

The marginal coil issue is not diagnosed with a code scanner, because as I said it rarely sets a code. As such, there is no requirement for the check engine light to be on. They will do a stress test. If none fail, then you have to pay the diagnostic fee. Almost never is it the case that none fail. Here's how the test is done.

Unplugging the O2 sensor will accomplish nothing. You have to remove it. The purpose for removing it is that now exhaust gases will be able to escape out the hole that the sensor was mounted in. If cat is clogged, this will relieve the back pressure enough to get close to normal performance out of the engine.

+1 for the above
OP you are right that it appears you are btwn a rock and a hard place on the $100 diagnostic fee, but if you have original coils it is almost guaranteed that at least two will fail, if not all of them.

 

[1LoudLS]

Im sorry, but if you cant figure this out with what you have been told so far and seen with your own scanner. then it sounds like the worse case scenario of $100 for a professional to tell you exactly what the problem is a damn good deal.

I was having the same code so brought my car in yesterday

He told me they stress tested the coils and they all passed.

I'm having my catalytic converter replaced under warranty... He called me today to say it's under warranty for 80K miles, I have 79+ so i'm lucky I brought it in when I did.
