7mge Timing

[Huz]

Hey guys, I’m just having some trouble with the ignition timing on my 7m. I have removed the dizzy while fixing some oil and water leaks. So since I have installed it and found TDC, I then set it to 10.

When I drove to work this morning on the f3 I noticed the car to be a bit sluggish going up the hills but not consistently. I have been talking to one of the mechanics at work and he said to advance the timing more if the engine has low compression. I haven’t tested it yet but I guess it would be pretty low as I can turn the motor over with the sparkplugs in.

Has anyone had any problems with this or could the problem be something different like leads or plugs.

Did you do it properly with a timing light and jumping terminals E1 and TE1??

Yea I used a timing light and jumped the terminals. I am staring to think that it might be the leads or something and just a coincidence that it happened at the same time. I can feel the car shaking slightly when this happens so maybe its the knock sensor.

i'd say its probably leads.. maybe a bad connection or they might have even gotten damaged when you removed them. just check the rotor button, dizzy cap and leads. when you say it's 'shaking', it's misfiring. i wouldn't just go and advance it on a hunch like that since it's set to where it's supposed to be already.

Your right about it misfiring it must have just been a coincidence that it happened at the same time I am going to change the coil lead and the plugs this weekend, thanks for that

Check the resistance of the leads before changing them as they may not be the problem & could save you some money.
Check the dizzy carefully as you may have a hairline crack in it.
10 degree timing is good & there is no advantage in advancing/retarding it.
