Help, Please!

I have a 1994 Landcruiser and am the second owner. I have owned it since 1998 when it had 96,000 miles on it. It currently has 177,000 miles. I am getting an error code 28 when the light goes on, which is not all the time. I have replaced the plugs, wires, rotor, distributor cap, fuel pump and filter, ignition coil, and ignitor, and ECU. It boggs when I press the accelerator, misses, has no power and the gas smell is awful when I turn it off. It also sounds like something is loose in the fan/belt area, but I can't find anything. I have searched every inch of this site and have decided I need a good, honest mechanic. I live in Riverside, CA. Any suggestions?

Thanks,
Debbie

Code 28 is the heater circuit in the O2.

Since the codes on the 94 are incremental, if you don't have a 25/26code (air fuel mixture) which should code before 28, something more basic is the problem.

This sounds like a classic case of fuel leak. Ck the connections at the fuel filter first, then follow the lines from the tank to the engine, looking for wet fuel spots. If you smell fuel, it should be traceable. This would cause the symptoms you describe.

If no, ck vaccuum connection at the fuel pressure regulator, make sure your plugs are tight, make sure your wires are routed correctly.

Again, this sounds like a basic fuel leak problem.

Sounds like a bad O2 sensor to me. I've had to replace both of mine and it seems that cold weather brings it about. How old are the ones in your truck?

Sorry, the code is a 26! I don't know why I keep saying 28. I took out the charcoal canister today and did the test like the book said. It looks like it's bad since the air comes out of both the tank side and the purge side. I will take it to the dealer to verify before I order a new one. But, somehow I don't think this is the end of it.

Sorry for the earlier error in the code.

Thanks,
Debbie

The canister would make sense if you are smelling ags. Price one out with CruiserDan before going to the dealer. His price might make sense to go with your own diagnosys and skip the cost of having the dealer get involved.

Code 26 is O2 sensor, replace. Charcoal canister - make sure you have done the vacuum vs pressure cks correctly. If replaciing CC, make sure you replace the gas cap too. In fact, before I'd do much else I'd make sure you do the gas cap tests first.

IME, if a charcoal cannister fails, it's usually due to some other issue, like a bad ck valve, electric vacuum switch that is defective, and/or a bad/aftermarket gas cap.
