[lubedealer at juno.com]

Have a '87 5000SQ... (172,000 miles)  5 speed
Cold compression is around 190 lbs & varies 7 lbs accross the 5
cylinders...
New Audi plug wires & plugs...
Car will start & run fine most of time...
If it sets a couple of days it will start OK but have a bad miss & smoke
like crazy (did this morning on me)
Trying to sell the car but seems to go crazy each time I fix another
problem...
I have replaced the fuel pump & it is OK....
Any suggestions in what to look for..???______
Many thanks in advance...
