88 should have the 9th injector for cold start, maybe it is going bad. Is it only when the car is cold ordoes it happen warm also?

For the timing you will need a timing light. Hook up to the battery and #1 spark plug wire and on the driver side above the crank pulley should be a metal tab with numbers on it. You may have to get the wire brush and some PB to clean it to see the numbers. The numdbers are the degrees of timing with 0 obviously being 0. Positive timing is to the left (If I remember correctly) and negative is to the right. Point the light at it and look for the line on the crank pulley and see where it lines up to relation of the metal indicator and that is your timing. To adjust it you loosen the distributor hold down and turn the distributor left or right. Check it, then adjust again if necessary. Not sure optimum for a TPI (sure someone here can help you with that) but +3 degrees is a pretty good start.
