86 Martinique bad idle after about a hour Printed From: CorrectCraftFan.com Category: Repairs and Maintenance Forum Name: Engine Repair Forum Discription: Engine problems and solutions URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=4266 Printed Date: November-23-2024 at 3:29pm Topic: 86 Martinique bad idle after about a hour Posted By: logicsound Subject: 86 Martinique bad idle after about a hour Date Posted: July-24-2006 at 2:39pm Been lurking for a couple weeks but first post. I have a 86 martinique with a 351. Everything seems to run great when cruising and even when idleing but after about a hour or so it wont start without giving it gas and starts to stall alot. If you let it sit for about 5 minutes it will start right up and idle normal but if you start going again and then return to idle it will stall again ? Steps taken so far. New plugs, and new wires. old plugs did not look bad, a little carbon but not much. Also maybe a stupid question but people talk about adding weight to increase wake what is the best way to do this ?

Double check the timing and makesure it's between 8-10 BTDC. I assuming it's not a point style dist and is electronic already, if not get a new dist or conversion kit to replace the points. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique Posted By: Tim D Date Posted: July-24-2006 at 6:08pm Check the float. ------------- Tim D Posted By: logicsound Date Posted: July-24-2006 at 6:12pm Thanks I will try adjusting the idle, but sadly it is a points style dist. Are the conversion kits worth it or should I just get a new dist ?
