My 1988 Legend with 190,000 miles and automatic transmission has been
running rough.

I've replaced the spark plugs, plug wires and PCV valve. I've run Fuel
System Cleaner and changed the oil with Mobil 1.

It starts, cruises and turns off fine.

Yesterday, I drove from Central NJ to Northern Virginia covering 200
miles in three hours (66 miles per hour) and I averaged 25.03 miles
per gallon.

But around town, it seems to buck like crazy especially at around
1,700 RPM and 42 MPH under light accelleration.

Sometimes it idles fine, other times it idles rough.


Sincerest thanks in advance
