This bulletin cancels and supersedes dealer service bulletin 88-40 (Section 6D) dated August, 1987. Symptoms have been expanded to include Code 43, Surge and Misfire. All copies of 88-40 should be discarded.
Some vehicles equipped with 5.0L, 5.7L and 7.4L engines built with distributor, P/N 1103698, may exhibit a rough running engine condition, surge, misfire and/or Code 43. This condition may be the result of oil ascending the distributor shaft and accumulating inside the distributor cap.
If oil is found inside of the distributor cap, wipe the distributor cap, module and distributor base clean with a soft cloth and replace the distributor mainshaft assembly with P/N 10467353 per service procedures in section 6D4 of the appropriate Service Manual.
Parts are currently available from GMSPO.
