My 1997 80 series has what I can best discribe as a bit of a stutter. It seems to only happen or be noticeable when at freeway speed going up a good sized incline.
My truck has 102,000 miles. The supercharger was added about 3 years back at about 88,000 miles. I believe the stutter has been there most of that time. I have a long trip planned that will have some mountains to climbs so I want to try to figure this out prior.
I took it to a local Toyota shop and they did/checked the following. 3 degrees of timing, it has the cooler MR2 spark plugs, they listened to the fuel injectors with a stethoscope and they all sound the same, they ran it up and down a large freeway hill where the stutter takes place with a diagnostic computer hooked up and no diagnostic codes popped up. The check engine light is not on, they changed the engine compartment fuel filter... The problem is still there. These guys are recommending finding either a Landcruiser supercharger expert or a supercharger tuning shop.
I don’t know where to turn. Any advice would be appreciated.
