Hey Derek, if there are no codes, then it's usually a fuel delivery/
ignition thing....Can't tell you how many people/myself included,
solved wierd things by replacing caps/rotors that looked fine. Not
sure what the problem is, but the caps carbon up really quick. Plug
wires tend to get old when they are $200+ a set, and my experience is
that fresh wires make a big difference in a perfectly running car.
If you've got the Bosch plugs, try the Autolite 103's($2/each?) that
a "prophet" told me to run years ago....Ha...cheap way to rule out a
bad plug, and for some bizarre reason, seem to run better than those
$100/ 4 prong ones I bought years ago and have them in both my 5-
speed and my Lago. After seeing what was in the last parts cars fuel
tank, I replaced both good cars filters even though they were newish/
low miles after seeing all that funk in the tank. Not sure if it's a
coating or what, but 1/2 coffee cup full of black flakes/goo and it
was stuck to the filter screen on the pump. Unless someone's been in
there, there's 22 yrs of funk in a tank that's not very fun to
remove.....When I do my 5-speed overhaul sometime soon, injector
cleaning/replacement is in it's future since I"m sure it would
benifit, but runs fine......Tom
