1994-4cyl.Camry(Cali)/auto/199,999 miles seems like an EFI problem. Engine will shut off while driving, feels like it's running out of fuel. Replaced EFI relay under the hood, ran for 2 weeks and now...


"Distributor issue"??? Thats very vague.
Go here,
extreme-check-engine-light-codes.com
and there should be an explaination on how to get the codes yourself. Or get the exact code or codes from Goodrich and come back here and let me know what it is.
Most auto parts stores will check for codes for free. They may or may not do pre OBD II cars. Worth a try.

2005 toyota camry lost transmission at 45,000 miles and 6 mo. out of warranty. How much should a new transmission cost? Shouldn't Toyota cover this at such an early date


With just 45,000 miles, it shouldn't of went out this early. It just depends where you buy them and if you buy them new or used. You can get used ones for a few hundred dollars. A new one is going to be around 1000 I would say. Like I said, it may be a little more or a little less. Everybody charges different prices. I would call and make sure there is not a recall on the tranny for that year. It can't hurt.

I have p0420 on my 06 pont gp gt. it mostly comes on after I slow down after highway


Here is the trouble tree for that code it is most likely a bad cat but follow the trouble tree to see where it lead's you.
DTC P0420 or P0430

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. See: Testing and Inspection\Initial Inspection and Diagnostic Overview\Diagnostic Starting Point - Vehicle
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

DTC P0420

* Catalyst System Low Efficiency Bank 1

Important: A new converter with less than 100 miles on it may set DTC P0420 or P0430 due to out-******* of the internal matting. Operating the vehicle at highway speeds for approximately 1 hour may correct the condition. Hope this helps

My 2007 Toyota Camry just hit 45,000 miles and my check engine light came on. Would regular maintenace needed cause the light to come on? What should I / could I expect when I take it in?


I do believe there is a difference between a maintenance light and a check engine light. You can take your vehicle to most parts suppliers (auto zone, pep boys) and they will check your computer codes for free.

Engine check light read p0171 and p0420, noticed a leak of engine oil on cylinder 2 area of head gasket when checking the sparks plug, is that the cause?


P0171 code is described as: lean condition bank 1, oxy sensor 1. If your vehicle is a 4 cylinder, which I believe it is.. you have got a lean air/fuel mixture being found by the ecm(computer).This can be caused by several things. The first of which is a possible vacuum leak at or near the intake manifold. This can also be caused by a MAF(Mass Air Flow) sensor problem or even by something as simple as a clogged fuel filter. This lean condition could also be the cause of the P0420 :described as a catalyst efficiency problem. It would be best to have the vehicle taken to a reputable repair facility that is capable of engine performance diagnostics and have them run tests for these codes. The gasket you mention is most likely a valve cover gasket not the head gasket and would not cause these codes. Although you should have this leak fixed before it becomes a problem.

Hope this helps..

Engine light came on. The dealership said it was diagnostic code P0420 and that it would cost @ $1,200.00 to repair. This seem pretty high. What is this diagnostic code about and is the repair rate


Hi, this code represents a Catalyst System Efficiency Below Threshold (Bank 1). and the repair, considering that it will be repaired by the dealership, seems to be in the normal cost range. The labor is what usually inflates the price when dealing with catalytic replacements.

You could probably get a better deal by taking it to a non dealership type of repair shop. This may cut at least 200 dollars of the original dealership quote.

Please rate and god bless:)

P0420 is a cat code. Sometimes, you can replace the upstream & downstream air/fuel & O2 sensors, run some good fuel injection cleaner thru it, and that might fix the problem. If not, you may need to replace the cat. Note that the cat is covered under warranty for 8 yrs/80,000 miles. Toyota will replace it if it has gone bad, for free.
