How do you know the turbo is bad in a 1988 t-bird
Hello there and welcome to fixya
Turbocharger problems are some of the
most difficult to troubleshoot. The main purpose of the turbocharger is
to provide more air to the engine. The more air going into the engine
the more fuel that can be burned, which results in an increase in
horsepower. There are four main parts of the turbocharger: the
wastegate, center rotating assembly, turbine housing and the compressor
housing. By understanding how the turbocharger functions, it is possible
to uncover the causes of problems.
Check the air filter element
as this is a main cause of blue exhaust smoke. This blue smoke occurs
when there is not enough air going into the engine. Check all ducts and
pipes for obstruction or leaks.
Clean the turbocharger. Dirt
that has caked onto the compressor wheel or the diffuser vanes can cause
all types of problems. If the turbocharger is very dirty or the center
housing contains sludge then you should also check the filters. Dirt
coming in to the turbocharger is most likely due to broken filters.
Check with the engine manual to
ensure that the camshaft or pump is working at the correct timing.
Adjustments may need to be made as the turbocharger can change over
time. If the turbocharger is out of sync,
then this will result in a noticeable decrease in engine power. An
additional cause of decreased power is a gas leak in the exhaust
manifold or the turbine outlet duct. The less gas the less power that is
Check the turbine blade and
compressor for any damage such as indentations or notches. This type of
damage will cause screeching noises, whining noises, rattling and
scraping sounds. You will need to replace the turbocharger as well as
locate the source of the damage to prevent further damage. There is a
chance that the noises are due to other eternal components and not the
turbocharger, but a visual inspection is easy to check before moving
onto other components.
Inspect the actuator if the
entire turbocharger is frequently overboosting or underboosting. Make
sure that the actuator is not loose and if so tighten it to the
specified torque values. If there is visible damage to the actuator and air leak or if the actuator spring has broken a new actuator is needed.

How do i remove the drivers side exhaust pipe
The best way if it is damaged is to take it to a muffler shop. They are pretty reasonable and they have the special tools to do the work and the knowledge. The bolts and nuts get rusted and sometimes break off. if you need to just take a section off then there is a special tool to cut the muffler pipe and then you have to weld on a new section. When the bolts break of it becomes a real job. You may have to take the exhaust off the engine block and do it where you can get to the job. Sorry, but I need more information to give you more directions.

Horn and cruise contol
Sounds like your steering column wiring harness has come disconnected. Check the condition of the connector, which will be located between the brake light switch and the instrument cluster, plugging into your steering column. Also, check the ground connection at the steering column (single black wire).
