RE: Smog Problem on '91 Jetta GLX

["Viva Soccer" <viva_soccer@hotmail.com>]

Marc/Dave,

The cat has been replaced.  The exhaust is stock.  I also replaced the
rear fuel pump last year.  Here is something else that might help us
understand.  Before I replaced the starter ignition switch, I got this
problem...  I would be driving down the road and all of the sudden it
felt like the auto-choke would kick in.  I felt like I would lose power. 
I would turn the key off and refire the engine.  Boom, problem gone...
until a few mile down the road when it would happen again.  I have
replaced this switch and the problem just started to occur again.  Do you
think this is now pointing to something eletronical that I haven't
replaced - like the ECU?  Or could there be some other component that I
am not troubleshooting?
