I was given the rong dist. Cap when replacing. The rotor scraped the dist. Cap and my truck has lost power and drives very bad, compared to before the mistake. I have also lost a great deal of my gas mileage. I took it to a shop to check the timing, they helped some but it is still lacking power and gas mileage. The shop also told me that they could not get my timing set back to 10 degrease as the specs call for. They could only get it to 8 degrease. Also when I run my a/c it looses even more power. I am the only owner of this truck and I know that it is not running properly. Also when I got my truck back from the shop I did notice that the distributor has been turned almost all the way up. It is running better than it was at first, but it has not been fixed properly. If the distributor has been turned up will it strech my timing chain? I have driven the truck for around a year like this. Please help. I would really like to get my truck running right again. Thank you.

Hi shanun,

Thank you for the donation.

If the distributor assy is original and has not been replaced before, I would suggest checking the vacumn advance mechanism. A leaking vacumn or a stuck advance mechanism would cause the timing to be out of specs.

I am not sure if the distributor is fixed slotted or has gears. If it is equipped with gears, and the vacumn mechanism is in good order, most probably the distributor has been installed out of alignment by 1 tooth. This can be rectified by pulling up the distributor and advancing the rotor by 1 tooth and reinstalling.

Incorrect ignition timing would cause performance and fuel consumption issues. Timing chain would be more likely to be affected by wear over use rather than the ignition timing.
