Clogged injectors

Re: 1986 Sunrader, 22RE, auto, 58K miles;

Recently the Sunrader stopped moving on US#6 in Indiana. The engine would run but no power. Had it towed to Fort Wayne and the diagnosis was rust in the fuel system. Had the tank removed and found it was too rusted to coat. So had new tank built, replaced injectors and had fuel rail cleaned. The injectors were corroded and plugged. Only one was admitting fuel. The fuel rail was very badly clogged with deposits and only one orifice for the injectors wasn't completely blocked.

So, check your fuel rail when convenient. It's better than experiencing what I did. BTW, the Sunrader has more power and runs much smoother than before the repairs.

No mention of fuel filter in your post. Did you physically see the damage to injectors/fuel rail?

my thoughts exactly. fuel filters are a very good thing. My 1991 toyota has one underneath about under the passenger seat.
