Re: 30,000 mile maintenence

["John Hervey" <dherv10@xxxx>]

Jim, I'll throw in my 2cents worth. I have said before about how an 
electrical tune up can perk up the performance to the car. Electrical 
parts do wear out as well as break. Ignition coils will develop cold 
solder joints and corrosion then electrically open when they get hot. 
Replacing the coil is a good idea. Wires will get old and develop 
carbon tracks as well as the distributor caps and rotors. You might 
want to think about the plugs also. I' am offering some hotter plugs 
on my web site and will be experminting with them also. We used to do 
this all the time when i worked on corvetts and for the type of town
driving we were going with our De Loreans, I think the plugs are to 
cold. I'll probably catch flack over this, but i'm going up the line 
with hotter burning plugs. I will put more info on my website as soon 
as I can get permission from Bosch to copy the info. If not I will 
have to rekey it. Don't forget The Fan Fix, it to can increase 
performance. Let me know if I can help.
