Back on track!

Well after a few weeks of not being able to work on my car, partly 
due to the fact I broke my only ignition key (DOH!) and also 
partially shaving the tip of my pinky off with a power planer (ouch!) 
I am back in the game. I'm happy to say I got a new key cut by Rob 
Grady and I'm getting back into working on my car (doing very small 
things until my finger recoups). 

Anyway here's the deal: I can start my engine with no problems but it 
does have a slight back firing problem in the high RPM's. I know it 
can be anything causing it but here's what's happening....I don't 
think my Frequency Valve is not functioning...I don't hear it buzzing 
while the engine is idling or when I rev the engine up...could this 
be what's causing my backfiring problem? Also...when I connect a 
DWELL meter to the diagnostic plug (to the same circuit that's for 
the Frequency Valve) I don't get any readings (as one website 
describes and a few Bosch K-Jet repair manuals say)...could I have a 
faulty computer?? Also another strange thing...I let my engine idle 
for a few minutes today....when I went to turn the ignition off the 
engine was still running after I turned the key to the off position 
and removed the key. I thought maybe there was something wrong with 
the ignition switch so I unplugged it....engine was still running. I 
next removed the RPM relay knowing that it would stop the fuel pump 
and kill the engine...that stopped the engine. This was the first 
time this had ever happened. 

I should note that my muffler is currently off the car and is 
probably not giving the required backpressure for the engine...the 
CAT converter is on though.

If anyone has any info...feel free to email me. If it was under 
different circumstances i would be diagnosing the entire system from 
top to bottom but I have to do minimal things and not fool around 
with the fuel system to much, I don't want to get gas in my 
wound...that would burn like a mother...anyway....any info would be 
appreciated.

Thanks,

Steve
