Heres what I wrote to dealer I brought car from:

If you remember, I brought this 2005 Camry last March of 2013 at XXXXX in XXXXX. It has an faulty engine computer rendering vehicle inoperable and useless. It died in the middle of traffic not too long ago, and I almost was t-boned. Then it died in the middle of the turn lane and I had to restart it three times to get it to a repair shop where they reflashed the engine computer. Now today, May 25th, it did it again! Right after I pulled out of my driveway it died on the road. Thank god I was not on Highway 94 otherwise I would have been rear-ended. I believe there is a TSB on a faulty engine computer for the 2005 to 2006 Toyota Camry and it should be covered under emissions warranty and this is a serious safety issue, I almost had my car smashed up the first time! Until this problem is fixed, I wouldn't feel comfortable taking it out on a roadtrip. Right now I have a 9 grand paperweight in my driveway, and in fact my 1996 F-150 has been much more reliable than this Camry.
I don't want this to drag on for a week, if its not covered under emissons warranty/by Toyota, I will just order a used engine computer and install it.

Help!!!

Im going to order a engine computer and see if the problem goes away.
When it died the second time, I had to restart three or four times to get back to my driveway where I left car.

 

Could you post a link to the TSB for this? Sorry you are having trouble. I wouldn't drive it either.

 

What engine, V6 or 4-cylinder?

 

4 Cylinder

 

PO 354 first time and again today.

 

Is this code P0354? This is for the ignition coil on the No 4 cylinder.

Swap the coil with another cylinder and note if the code follows to the new cylinder.

Can not find any service bulletins on your issue. It could be problems with the throttle body which is electric powered not cable. Or coil issue and misfire.

Suggest cleaning the throttle body. The internet has many posts on how to do this. The engine model is a 2AZFE.

 

It has a brand new coil in #4, and it ran fine after being reflashed the first time, month maybe?

 

Reflash?

Swap the coil and determine if the code follows the coil.

Actually the engine computer was reflashed after the first time it died on me. I replaced the engine computer with a used unit but same exact version. 100 miles and no CEL so far. That's more than the 5 miles I went after I disconnected the negative overnight.
