I used the timing light on another vehicle and it worked OK, so I don't think it's the light. I was messing around again today with the MX-3's timing and it maxed out at 8° Now the kicker was I also checked it in the normal loop mode (ECU not grounded) and the timing did not adjust! It varied at aro...

I just noticed that the shop manual mentions the TDC timing reference mark assy is mounted on the timing belt cover. But I really did not think that it could be the problem anyway.

Pat, I am using an older induction triggered timing light. Any chance for the engine's timing marker itself (the strip with the TDC markings) to shift out of position? Is it mounted on the belt cover or cast on the engine block? I though about having the repair shop look at the timing but I swore th...

I know what you mean about some repair shops. Seems to me that the labor rates keep going up while service quality keeps going down. As mentioned, I had a local shop change the timing belt and even though I never changed a timng belt before I regret not doing the work myself. I would also have been ...

Pat I did not check the cam/crank timing since the work was done by a service shop. The car runs fine though. Would 1 or 2 notches off have a noticeable adverse effect on engine performance? If not, I guess It may be the problem.

I guess a few degrees off should not be a big deal, but the base timing should be checked and set once the disty is removed or replaced. Unless the ECU is in service mode it will always try to adjust to programmed timing as equired, which is a good thing. I'm just wondering why my disty is maxed out...

Yes, per shop manual procedure. No offense taken. I read probably most of the posted topics that I could find on base timing and I was surprised that no one has had this problem since disty failure is very common. So I decided to post it. Perhaps we can figure out whether it's the replacement part o...

Thanks for your reply Pat. The motor runs OK, but it seems to lack a bit of power. I'll have to get my hands on an OEM disty and see if it makes a difference.

:?: I'm wondering if there is a solution to why the base ignition timing is maxed out at only 7 degrees BTDC. I installed a replacement disty (AutoZone part) after the original failed and followed the procedure in the manual to set the base timing. The disty reached as far as it will twist and it on...
