View Full Version : Sick Marauder Needs Help!

Well, this is part rant and part plea for diagnostic help.
Yesterday my MM with 71 K got a Check Engine light for the first time. OK, I was planning on taking it in for an oil change this morning anyway. My regular service advisor wasn't there, so another guy says that they will change the oil and check the code on the light.
After waiting too long, I go to the guy and ask what's going on. He tells me that when they hooked up the computer to my car, it came up with a code for the MAF, but then it blew the computer on the car, and now the car won't start. I'm not too happy about this, and we begin to talk about the situation. He talks about reprogramming the computer, and I tell him to take out my chip first so it doesn't destroy the programming on it.
A light goes off behind his eyes. "A chip! Now we can blame the electronic problems on the chip!", he's obviously thinking.
I said, "Not so fast, this car has had diagnostic computers hooked up to it a number of times since that chip was put in over 65K ago, and there has never been a problem. It's not the chip."
Well, after much fiddle farting around, they take out the chip, and download another program into my computer. The car starts.
They explained to me (and it sounded fairly reasonable AT THE TIME), that Ford has a new computer program for these cars. The chip I have was put in with the old factory program, but isn't compatible with the new program. So I drive away, chip in hand, thinking that I just need to buy a tuner ( see above thread) to put in a better program like so many people here have done. Wrong.
After awhile, the car starts acting "sluggish." I expected it to act less responsive without the chip, but this is something else.
I can punch it from a dead stop, and it almost just sits there. It accellerates VERY slowly, and at WOT you can see the RPM's increasing while the car is barely accellerating at all. It's like the engine is OK, but the power isn't being transferred to the transmission. Finally, about 5500 RPM's, something "catches", and it takes off like it's supposed to.
I know that these guys at Southwest LM in Houston screwed something up. This is obviously NOT the new MM program from Ford!
I need to get this fixed ASAP. I will, of course, be taking it in Monday morning. But in the meantime, I don't even know how much damage I might be doing to something by driving it like this.
Any suggestions on what to look for?
Thanks in advance.

Try plugging your chip back in and see what happens.

OK, I went outside, plugged the chip back in, and the car wouldn't turn over. Pulled the chip out, and it started.

I'd get that car right back to the dealer! You may want to have it towed.

That is one advantage of having a tuner, you can restore your program and remove what the dealer did. Sorry I was no help.

Unless the tech knows what he's doing, ALWAYS unplug the chip before turning the car over to them. I would imagine he tried to load the new program while the chip was still plugged in and blew the chip. As for the other problems, sorry but I'm no help.

Hey Ross!-

Good to hear (read) from you again. If it was me, I'd take it to Strictly Performance and tell them your story. They can re-burn your chip and you'll be normal again.

Good to hear from you again, Ross.

Sorry I can not help you if your situation, just wish you the best of luck in getting it resolved.

check one of your fuses. Did you remove the ignition fuse when you took the chip in or out? Let alone disconnect the battery when you did that? Something must have blew. Just a guess. I had a fuse go and when the chip was in my car the car thought I was trying to steel it and it would never start. Even with the chip gone it still wouldn't start. So I went with a superchips microtuner and out when the jet chip. Something seriously sounds wrong though, but I bet it's the computer. Ask the dealer to hook it up again. I bet it's sending the wrong siginal at the wrong time.

Ross, I think that what Fordnut has posted is right on the mark. Every time I go to the dealer, not only do I tell the service writer to tell the mechanic that I have a chip in the car, and that I do NOT want them to reflash the computer for any reason at all, I also tape a note written on a piece of cardboard right next to, or over the diagnostic port, which says..."This car has a chip installed in the computer. Please do NOT re-flash, or reset the computer settings!!".


I've heard that many dealers will just go ahead and throw a re-flash on your computer w/out even telling you about it beforehand, and that's why I take those precautions. So it sounds to me like they tried to throw a re-flash on your car with the chip in it, and they damaged the chip like Fordnut stated.

I have to "third" what FordNut and BillyGman said...even if you haven't had trouble before, as they say there's always a first time, and this may have been it for you.

Most likely the reason the car won't start with the chip installed is that the catch code no longer matches with the new programming. Get the chip reburned and hopefully you'll be good as new. You'll need to get the new code from your dealer.

The chip burning process does an erase, load, and verify, so if the chip HAS been damaged, the programmer will know that immediately.

If they reflashed your computer, somewhere the new code should have been posted. I've seen it before written on the air box, or circuit breaker cover. The 04 program is code MAV2. Could they have reflashed the computer to that? In which case the car would most likely not run with a chip from another code. Did they mess with the computer with the keys in the car? Thats another no, no, usually sets off the PATS and the car won't run.

If they reflashed the PCM for any reason there will be a retangular blue sticker about 2" X 4" either on the front cover in front of the radiator or on the underside of the hood. It will have the reflash info on it. I had by 300B reflashed to cure the cold run hesitaition, and on our numerour fleet CVPI's when they reflash for any reason, the sticker's still there. I think if they just reload the origianl factory program without an update the sticker is not needed. This is somthing to do with EPA regs...
