haydenmtaylor Posted October 17, 2016 Share Posted October 17, 2016 Hey everyone, Recently, I got back from a holiday and had my 89'GL sitting there for a month. It got driven a couple of times, but was dead when I got home. I replaced the spark plugs and she was up and running. Ever since though, it's ran like crap. Shakes with a very low idle, back fires when changing gears/de-accelerating and has bad fuel economy. I came to think it could just be time for a timing service. I have all the gear, new water pump (while I'm down there), timing light, compression kit etc and know how to test each thing.However, I'm just confused as to what order each part should be tested in? Disty, Ignition, Belt, Carbu idle speed?Cheers all!Hayden Link to comment Share on other sites More sharing options...
Len Dawg Posted October 17, 2016 Share Posted October 17, 2016 (edited) Is it carburetor or port? Check you spark plug wires.. I had them come off before.. runs like a turd unless we got all 4 connected and going to the proper location ha ha ha and if ya do the timing make sure to disconnect the green plugs..

lrgvanman Posted October 17, 2016 Share Posted October 17, 2016 The first thing I would check is your firing order...see if your wires are right...best of luck! 1 Link to comment Share on other sites More sharing options...
MR_Loyale Posted October 17, 2016 Share Posted October 17, 2016 Remove the distributor cap and wipe out the condensation. Also lightly sand tip of rotor with emery cloth. 1 Link to comment Share on other sites More sharing options...
subnz Posted October 17, 2016 Share Posted October 17, 2016 Sounds like it could be an vacuum / air leak. hoses etc http://www.aa1car.com/library/vacleak.htm or maybe ignition timing retadred (backfiring) - 8 degrees BTDC @ 800rpm with vacuum advance hose off distributor 1 Link to comment Share on other sites More sharing options...

haydenmtaylor Posted October 18, 2016 Author Share Posted October 18, 2016 (edited) Tested and checked all the vacuum ports and hoses and they all seem to be working just fine. Going to hook up the tachometer tomorrow and see what I can do timing wise. Edited October 18, 2016 by haydenmtaylor 1 Link to comment Share on other sites More sharing options...
BumbleBeast Posted October 18, 2016 Share Posted October 18, 2016 .. 8 degrees BTDC @ 800rpm with vacuum advance hose off distributor 8 on Carbureted models, 20 on SPFi models Link to comment Share on other sites More sharing options...
3crows Posted November 13, 2016 Share Posted November 13, 2016 Is the timing on an '86' EA82 with a Weber conversion still going to be 8 degrees BTDC? Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted November 13, 2016 Share Posted November 13, 2016 All the Weber swaps I've done on EA82's makes me to move forward the ignition timing up to 20º ... So, try to move it forward a Little and do test drives at different timings, to achieve the best results. Kind Regards. Link to comment Share on other sites More sharing options...
