ignition module

[302fordracer]

what would cause the ignition module to keep failing? my 1993 notchback started displaying the characteristic signs of a faulty ignition module (bogged hard and sputtered at 3500 rpms and the tachometer would fly all across the board, and it started only doing it when engine was hot progressively got worse and started acting this way all the time) so I replaced the distributor and bam problem solved...well now a couple months later the problem is coming back but so far it still only acts up when hot...Any ideas why this is happening?

Did you pull the codes out of the motor to see what is going on?

What kinda' distributor?

Do you have a MSD or any other type ignition box? That'll cause them to go quicker...just a suggestion. Especially if its a stock dis.

there is not an msd spark box however the coil is msd and no I haven't pulled the codes I don't have a code reader and I am not really familiar with how to do the koeo and koer tests anyhow. There is no CE light tho in case that helps..and the engine runs great otherwise...

you can purchase, or go to a library and check out a chilton mustang manual it will help show you how to retrieving codes and how to do it with a scan tool or an analog voltmeter method and it has various troubleshooting methods for diagnosing problems. check out various manuals and buy your choice repair manuals have been one of the better tools i own.

Even easier is to follow Jrichker's post here.

Good luck.

If you want to run a self-test and verify the system for codes, you don't need a scanner, check
- How to run a self-test and codes scan

In your case the distributor should be under its warranty period. I would check that MSD coil, though. My 2¢.

PS: And agree with Hissin50 on Jrichker's post (saw it after posting, Great!)

Don't be afraid to dump the codes... It will only take about 5 minutes and you only need a 2" piece of wire. The Check engine light will spit out the codes. No scanners needed!
