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

 

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..

The first thing I would check is your firing order...see if your wires are right...best of luck!

Remove the distributor cap and wipe out the condensation. Also lightly sand tip of rotor with emery cloth.

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

Awesome, thanks everyone! It's been driving me crazy.

All of those are simple but sometimes it's the little things right? Pain in the rump roast

I'll do all those things this arvo and get back to you guys

 

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.

.. 8 degrees BTDC @ 800rpm with vacuum advance hose off distributor

 

8 on Carbureted models, 20 on SPFi models

Is the timing on an '86' EA82 with a Weber conversion still going to be 8 degrees BTDC?

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.

Thanks, BB
