Hi Everyone,

I’m hoping someone can provide some help. I have aproject car that I bought and it doesn’t run well. Rough idle, lack of power, and stalling. I’ve been chasing issues on this car for some time now.

This car has TFS heads and a E303 cam. I’m starting to wonder if the cam wasn’t installed right or maybe the distributor wasn’t installed right. Maybe the balancer is wrong?

so I have the spout out to check the timing andim showing the initial timing as way over advanced. It’s actually showing above30 which doesn’t seem right because I don’t have any pinging issues. I tried to get some a pic as I might come off as a crazy noob on this. You can see the pointer is past 30 and would appear to be around 40 if it had mark

Balancer slipped?? Guy timed it to the center of the circle on the pointer. I see yellow in it. Look for a wobble. Set it to twelve for now, and see.

If I drop the timing the engine idle gets a lot rougher and the stalling gets even worse.

Start with the basics, pull the #1 plug and bring the piston to top dead center on the compression stroke. Pointer should be at 0*. Set rotor at #1 on the distributor, start the engine and set the timing starting at 12* and see how it runs.

Ok so I verified the balancer was good by bring the #1 cylinder to TDC and the balancer was at 0.

I happen to have a 2nd 5.0 sittin and decided to swap distributors. Bingo theengine now runs 100xs better. I think either TFI or PIP was bad. The TFI was an after market brand.

I have been chasing problems with this car for 3 years now. I have found and fixed some many issues from the previous owner when he redid the motor and top end.

I don’t want to jinx myself here but I might actually get to drive this car!

Basically no, start a thread in the tech forum detailing the work you did and why your balancer has no marks.
