Re: [DML] losing power

Larry,

A vacuum leak does make a car run lean. (Lean = not enough fuel for the 
amount of air, thus the unmetered air of a vac leak leans the car out.) It 
might also be a fuel delivery problem of some sort. This isn't very 
specific, but if someone competent has diagnosed a lean condition using a 
calibrated air/fuel meter then you need to determine whether the issue is a 
vac leak or insufficient fuel delivery.

Unfortunately there are numerous places where you can have a vac leak on a 
K-Jet, and likewise there are numerous potential sources of insufficient 
fuel delivery. John's suggestions are good for starters on the fuel delivery 
side.

I hate to say it, but if your exhaust was as hot as you say, you may have 
some serious damage.
