Question type: Maintenance & Repair

Changed distributor cap and plugs.checked
air filter and pretty clean.had a friend look
and says carb isn't clogged CU's tchecked
tailpipe. I then had a guy I work with look at
it and he also be lives its not carb or
Cadillac converter CU's o2sensor is reading
fine ..he then drove while his reader hooked
up and said that something about numbers
were jumping all over fro the -s to the +s,.so,
due to numbers he checked spider injector
and sensor plugged unto and sensor had
gasoline in/on it that apparently should not
be there,so he believes its the spider
injector, that one may be cracked and that
explains y my car is doing that.before I
spend money I don't have I like to know any
other suggestions of what it could be or it
could very well be spi injector.. Please any
suggestions ...

Need more info - what engine?


Hello - is it a 4.3 liter? If it is make sure you have fuel pressure( you have to read it at the fuel rail at the engine). If it is OK and there are no codes on the reader you should isolate the Catalytic converter. Temporarily separate the exhaust pipe in the front of the converter. You may need a mechanic to get this done.See if there is any difference in power with it disconnected.
