99 Astro Van: Had the complete distributor ( shaft ) replaced. Now I
have a misfire on cylinder 4. Idles rough at a stop, sometimes runs
smooth on freeway, then it will start missing, and jerking the car. Transmission checked out fine, rebuilt 2 yrs ago. Is it possible the
distributor wasn't put in correctly?
Yes it is possible to be a tooth off or more and still run but if one cylinder is misfiring then it may be a bad plug or plug wire pull that plug and see if it is worn out and try replacing the wire first. if the plug has a wide gap that can cause it to misfire. you may have a bad injector too but don't know for sure. This is one of them questions that need to be looked at physically to know for sure.
