at 240,000 miles my 2000 toyota land cruiser developed a miss/stall when at a stop. Went for the easy stuff first. Replaced fuel pump and filter not it. Cleaned the MAF and Throttle body nope still doing it. Replaced all 8 coil packs and plugs and its made it a day now without stalling so I am knocking on wood it is fixed. I have to admit Toyota did it right for changing plugs and coilpacks first time I have tried it on this car and from getting tools to putting them away less than 2 hours. I think its the first time I have ever not had a frozen plug or bolt when working on a high mileage car.
