It's reported this is under goodwill repair by TOYOTA who discovered this in their 1998 Avalon

Occasional problems on this vehicle are failures of the Engine, Charcoal Canister Evaporative (EVAP) Solenoids and the Mass Air Flow (MAF) Sensor. Problems with the Engine are caused when the engine oil gels. Engine oil gelling can also cause excessive engine oil usage. When proper maintenance schedules for oil changes are followed, oil gelling should not occur. Toyota has issued an 8 year unlimited mileage goodwill repair for this condition. Problems with the Charcoal Canister Evaporative Solenoids, or the MAF Sensor can cause the Check Engine Light to illuminate. The cost to repair the Engine is estimated at $4,500 for parts and $1,384 for labor. The cost to replace the Charcoal Canister Evaporative Solenoids is estimated at $268.51 for parts and $65 for labor. The cost to replace the MAF Sensor is estimated at $148.90 for parts and $58.50 for labor. All prices are estimates based on $65 per flat rate hour and do not include diagnostic time or any applicable sales tax

3/39/03 was the first time the check engine light came on and it was fixed by the dealer, but the light has been on three additional times since then. It is on now and the dealer wants to charge me $40.00 just to tell me what the problem is. I had already had a machine put on the vechicle and found that it is the egr 1 & 2. This has really become a pain in the ass. It seems like everytime I turn around now there is something wrong with the car. Granted it does have 95,000 mile on it right now, but that is really low mileage for a 1998.
