Can someone please give me a step by step way of doing a hard reboot please. I’ve searched and keep coming up with different ways. Want to try to see if this may solve my problem. Thx

 

 

I have three quick questions on this reset.

1. Is there a trick on how can I get my radio code before I do this?

2. I have heard that as a precaution you should put a diode or similar device to absorb the pulse. Anyone ever do this or have trouble frying their ECU?

3. If this does not work, where can I send an ECU to get rebuilt?

Thanks,
Ronk

 

I'm wondering why you want to do it at all?

Also, the "ECU" (PCM) is a very robust item so usually needs no repair. What's wrong with it?

 

Hi JagV8,

Was going to open up a new window after pulling my plugs, but where I have you available I will run with it.

I was forever getting lean on bank 1 and 2. Did a smoke test, fuel trim test and sprayed the whole engine down with carb, brake, either and MAF cleaner and addressed all of the air leaks i could find. Now I am still regularly getting bank 2 lean and sometimes bank 1 lean, so marginally better.

Did the 100k X type service and replaced the MAF sensor, EGR, brake booster hose and their o-rings, 4 O2 sensors, fuel and air filter, battery cables and the two large o-rings that usually leak. All in have a thousand into the cost of the car for five years use so didn't want to be bothered chasing one thing at a time. I did get O2 sensor codes in the past which is why i replaced them.

I have had the car 5 years and just hit 115k miles, so I figured I would do a new set of plugs and replace at least the upper intake gaskets while i am at it.

Any other ideas on the lean codes? Was thinking if all else checks out correct look into a new ECU if cheap enough. I do live in Florida and the car has hit a few nasty puddles and i am running out of ideas. Would be interested in any other thoughts as well.

Regards,

Ron

 

I'd stop suspecting the PCM unless you have seriously good reasons e.g. it's wet.

 

In the back of my mind i am wondering about the being wet, because I live in Florida. I did have the misfortune of hitting a big enough puddle that my feet actually got wet. Water pushed in from the splash around the power brake booster, but the car did not sputter, stall or die, so I am not 100 percent sure on the ECU getting damaged.

We are pulling the plugs and intake today and will report back with what we find.

As always, i look forward to your reply as well as everyone else's.

Have a great morning,

Ron
