mountainbikeak Posted January 20, 2005 Share Posted January 20, 2005 91 loyale almost 180,000 miles. After searching for some time I was unable to come up with a solution. Recently instead of my idle going right back down to 750 it kind of huvers at around 1000-1300 then finals at its own will drops back down to where it should be. I did have a problem with my idle surging and the engine light coming on, Thier were many threads about that and I wonder if this could be the same kind of thing? Also set my ignition timing, could I have done that wrong? Oh and it has been pretty cold here in alaska recently not sure what kind of effect that could have. Thanks Josh Quote Link to comment Share on other sites More sharing options...
MorganM Posted January 20, 2005 Share Posted January 20, 2005 Winter is so harsh on cars I would start by looking for a vacume leak. With as cold as it gets up there a hose could have easily cracked or snapped off. Strategicly squirt little bursts of ether (starting fluid) around your engine bay as its ideling. The idle will surge if it sucks any of the ether in through a leak. Throttle Position Sensor is another possibility. Make sure the wire harnes plug is on securly, all the wires are in good shape there, and that the TPS itself is secured to the throttle body. Some things to start with Quote Link to comment Share on other sites More sharing options...
torxxx Posted January 20, 2005 Share Posted January 20, 2005 egr selinoid..... look for code 34 on the ecu Quote Link to comment Share on other sites More sharing options...
mountainbikeak Posted January 20, 2005 Author Share Posted January 20, 2005 I've checked all my hoses, didn't look bad. I recently had to change my egr solinoid, I got one from the junk yard, the cel went off so I assume that fixed that. I'll check and see what codes come up now.

torxxx Posted January 20, 2005 Share Posted January 20, 2005 you said the cel went off.. did you reset the check engine light by disconnecting the battery for a minute? if you didnt the check engine light shouldnt have gone off. Quote Link to comment Share on other sites More sharing options...
mountainbikeak Posted January 21, 2005 Author Share Posted January 21, 2005 It was the second time the egr solinoid went out, the first time for sure as soon as I plugged the new one in the light went out. I'm pretty sure it did the same this time as well. I havn't made it out I have a damned geology exam tonight so I'm kind of stuck. Question on timing, when using timing light do you want the mark lined up with 0 or did I miss understand that? Thanks man for the help Quote Link to comment Share on other sites More sharing options...
torxxx Posted January 21, 2005 Share Posted January 21, 2005 timing light on a sooby.. unplug the vaccumn advance, set to 800 rpms, hook the pickup wire onto the number 1 spark plug wire. point the gun with the trigger down at the hole in the bellhousing where you can see the marks. the flashes will show a line where your timing is 0 means 0 degrees timing.. you have a SPFI EA82 so yours should be @ 20 degrees Quote Link to comment Share on other sites More sharing options...
MorganM Posted January 21, 2005 Share Posted January 21, 2005 Slightly different here on a Loyale....SPFI so no vacume advance. Plug in the two green connecters under the hood up by your fuel filter on the drivers side. This will keep the computer from trying to advance your timing. The rest of what Torxxx is describing is dead on. Prolly need to reset your timing if you set it to 0 instead of 20. I find it helps to use a white crayon or chalk to mark the 20 degree line. REALLY shows up under that strobe light.... better than a dirty, crusty old flywheel Oh don't forget to unplug those connectors when you are done.

mountainbikeak Posted January 21, 2005 Author Share Posted January 21, 2005 Thanks for the input guys, I'm learning slowly but surely. I'm still a better fishing guide than I'll ever be a mechanic!! Thanks again Josh Quote Link to comment Share on other sites More sharing options...
Microracer Posted February 5, 2005 Share Posted February 5, 2005 timing light on a sooby.. unplug the vaccumn advance, set to 800 rpms, hook the pickup wire onto the number 1 spark plug wire. point the gun with the trigger down at the hole in the bellhousing where you can see the marks. the flashes will show a line where your timing is 0 means 0 degrees timing.. you have a SPFI EA82 so yours should be @ 20 degrees How do you actually change the timing? Do you twist the dist? And if so which direction? Really pinging bad under load and want to try a timing adjustment to fix it, thanks!

torxxx Posted February 5, 2005 Share Posted February 5, 2005 there is two bolts holding it down.. loosen them slightly. turn the disty counterclock wise to retard the timing. this will fix your pinging problem Quote Link to comment Share on other sites More sharing options...
Skip Posted February 5, 2005 Share Posted February 5, 2005 Back on the original poster's problem i.e. all highjacking aside The IAC could very well be your problem. Please see this post for a discussion on this item. I still think it should be covered under "periodic maintenance" Idle problems with SPFI's Quote Link to comment Share on other sites More sharing options...
