My 01 Camry with 73,000 miles stalls at lights/stop signs. Dealer tells me that the ECM and four fuel injectors need replacing to tune of $3000. Any advice?

Our 2000 Camry LE V6 (Japan-made) now has over 170K miles on it, and is still running flawlessly, consistently delivering between 25-28 MPG. The engine has never had the valve clearance adjusted (solid bucket tappets, adjusted by shim plates). The engine idles very smoothly, and there is no significant valve noise. However, I'm concerned about the need for a valve adjustment, and the possibility of inadequate valve clearance eventually causing a burned valve. It's almost inconceivable (to me, at least) that a non-hydraulic tappet engine could run for 170K+ miles without any significant wear in the valve train that would require valve adjustment. Does anyone have any input on the typical mileage where the 1VZ-FE 3.0L V6 engines require valve a adjustment? Has anyone every had a valve adjustment performed on a 1VZ-FE engine? If so, at what mileage? Has anyone ever experienced a burned valve on the 1VZ-FE engine? If so, at what mileage? Thanks! Quarkster |

Replying to: bma3 (Aug 18, 2009 4:56 pm) (It would be useful for you to specify if you have a 4 cylinder or 6 cylinder engine; failures and fixes may be different for the two engines.) First, it is EXTREMELY unlikely that the ECM and multiple fuel injectors would fail simultaneously. If you use good quality fuel, injectors should last at least 150K miles. EMC failures are extremely rare, unless the car was a hurricane salvage vehicle. I would NOT trust this dealer's diagnosis, and especially the $3K repair estimate. Camry's have a known issue with sticky Idle Air Control Valve (IAC valve) that causes stalling symptoms similar to what you describe. This is generally more frequent if you do lots of stop-and-go driving, or mostly short trips. The valve can be easily cleaned with a can of spray cleaner (like CRC brand Mass Airflow Sensor Cleaner), and should operate correctly for at least 25-30K miles between cleanings. The dealer will NEVER clean a valve, they will always want to replace it at $200-$250 or more. Here is a recommended list of things to do & check. If you can't perform these operations yourself, find a reputable Toyota independent repair shop, or try a different dealer: 1. Verify that the Idle Air Control Valve is functioning correctly. The most common symptom of an IAC problem is very low idle speed (500 RPM or less) immediately after a start (can be at cold start, or after a hot re-start). Problems with the IAC usually don't trigger the "check engine" light. 2. Replace the fuel filter; 3. Run several bottles of a quality fuel injector cleaner (Chevron Techron Concentrate Plus) through several consecutive tanks of fuel. This should remove any significant deposits from the fuel injectors. 4. Check the operation of the Exhaust Gas Recirculation Valve. Any defect in the EGR valve may also cause idle speed & stalling problems. ERG problems may or may not trigger the check engine light. 5. If it's a 4-cylinder, have a compression check done. Some of these engines develop a valve clearance problem (zero clearance) on one cylinder that can prevent the valve from closing completely, causing rough-running or stalling. This is easliy corrected via a valve adjustment. 6. If you are not doing so, switch to a "Tier One" gasoline. These are gasoline brands that have passed rigorous engine deposit testing by car manufacturers. Check on-line for the latest Tier One listings. Use whatever GRADE of gasoline is recommended in your owner's manual (regular 87 octane for almost all Camrys). Let us know what you find, and what the "final fix" is. Regards, Quarkster |

Oops .... The Camry described in post #573 is a 1998 model, not a 2000. I was somehow thinking of my 2000 4-Runner when writing about the Camry. Actual mileage on the Camry is now 177,000 miles. Quarkster |

Hi All, I am looking to get a good price on struts for my Solara 99 V6. Where on the internet is the best place to get toyota parts? Thanks. |

| My 2008 4 cyl. Solara states that 5W 20 or 0W 20 should be used, however some of my neighbors stated that the Toyota dealers have put 5W 30 and 10W 30 in thier engines when taken in for service. Will this cause engine issues? | |
