Re: lambda question

[jtrealty@xxxx]

When it warms up pull the plug on the cold start valve and see if that 
helps. Make sure that the three brass adjusting screws are LIGHTLY 
seated. Make sure that at idle the idle micro is working,(test with a 
meter). Try never to twiddle the mixture screw, it is very sensitive 
and can only be properly set with an analyzer. Check all of the vacuum 
hoses for proper routing and brittleness. If they get hard they crack 
and leak and it is very hard to find. Make sure that you have a good 
seal on the plug over the mixture screw, an air leak there will screw 
up the air-fuel ratio. Do all of the simple stuff before you mess with 
the lambda circuit, if it is buzzing it is probably OK.
